A sizeable fraction of the driver updates are simple bug fixes (and lock reworks for bug fixes in the case of lpfc), so rather than splitting the few actual enhancements out, we're just adding the drivers to the -rc1 pull. The enhancements for lpfc are log message removals, copyright updates and three patches redefining types. For qla2xxx it's just removing a debug message on module removal and the manufacturer detail update. The two major fixes are the sg teardown race and a core error leg problem with the procfs directory not being removed if we destroy a created host that never got to the running state.

Commit c33621b4c5ad ("x86/virt/tdx: Wire up basic SEAMCALL functions") introduced a new instance of core-y instead of the standardized obj-y syntax. X86 Makefiles descend into subdirectories of arch/x86/virt inconsistently; into arch/x86/virt/ via core-y defined in arch/x86/Makefile, but into arch/x86/virt/svm/ via obj-y defined in arch/x86/Kbuild. This is problematic when you build a single object in parallel because multiple threads attempt to build the same file. $ make -j$(nproc) arch/x86/virt/vmx/tdx/seamcall.o [ snip ] AS arch/x86/virt/vmx/tdx/seamcall.o AS arch/x86/virt/vmx/tdx/seamcall.o fixdep: error opening file: arch/x86/virt/vmx/tdx/.seamcall.o.d: No such file or directory make[4]: *** [scripts/Makefile.build:362: arch/x86/virt/vmx/tdx/seamcall.o] Error 2 Use the obj-y syntax, as it works correctly.

2024-03-29selftest: tcp: Add bind() tests for SO_REUSEADDR/SO_REUSEPORT.Kuniyuki Iwashima
This patch adds two tests using SO_REUSEADDR and SO_REUSEPORT and defines errno for each test case. SO_REUSEADDR/SO_REUSEPORT is set for the per-fixture two bind() calls. The notable pattern is the pair of v6only [::] and plain [::]. The two sockets are put into the same tb2, where per-bucket v6only flag would be useless to detect bind() conflict.

2024-03-29selftest: tcp: Define the reverse order bind() tests explicitly.Kuniyuki Iwashima
Currently, bind_wildcard.c calls bind() twice for two addresses and checks the pre-defined errno against the 2nd call. Also, the two bind() calls are swapped to cover various patterns how bind buckets are created. However, only testing two addresses is insufficient to detect regression. So, we will add more bind() calls, and then, we need to define different errno for each bind() per test case. As a prepartion, let's define the reverse order bind() test cases as fixtures.

2024-03-29tcp: Fix bind() regression for v6-only wildcard and v4(-mapped-v6) ↵Kuniyuki Iwashima
non-wildcard addresses. Jianguo Wu reported another bind() regression introduced by bhash2. Calling bind() for the following 3 addresses on the same port, the 3rd one should fail but now succeeds. 1. 0.0.0.0 or ::ffff:0.0.0.0 2. [::] w/ IPV6_V6ONLY 3. IPv4 non-wildcard address or v4-mapped-v6 non-wildcard address The first two bind() create tb2 like this: bhash2 -> tb2(:: w/ IPV6_V6ONLY) -> tb2(0.0.0.0) The 3rd bind() will match with the IPv6 only wildcard address bucket in inet_bind2_bucket_match_addr_any(), however, no conflicting socket exists in the bucket. So, inet_bhash2_conflict() will returns false, and thus, inet_bhash2_addr_any_conflict() returns false consequently. As a result, the 3rd bind() bypasses conflict check, which should be done against the IPv4 wildcard address bucket. So, in inet_bhash2_addr_any_conflict(), we must iterate over all buckets. Note that we cannot add ipv6_only flag for inet_bind2_bucket as it would confuse the following patetrn. 1. [::] w/ SO_REUSE{ADDR,PORT} and IPV6_V6ONLY 2. [::] w/ SO_REUSE{ADDR,PORT} 3. IPv4 non-wildcard address or v4-mapped-v6 non-wildcard address The first bind() would create a bucket with ipv6_only flag true, the second bind() would add the [::] socket into the same bucket, and the third bind() could succeed based on the wrong assumption that ipv6_only bucket would not conflict with v4(-mapped-v6) address.

2024-03-29tcp: Fix bind() regression for v6-only wildcard and v4-mapped-v6 ↵Kuniyuki Iwashima
non-wildcard addresses. Commit 5e07e672412b ("tcp: Use bhash2 for v4-mapped-v6 non-wildcard address.") introduced bind() regression for v4-mapped-v6 address. When we bind() the following two addresses on the same port, the 2nd bind() should succeed but fails now. 1. [::] w/ IPV6_ONLY 2. ::ffff:127.0.0.1 After the chagne, v4-mapped-v6 uses bhash2 instead of bhash to detect conflict faster, but I forgot to add a necessary change. During the 2nd bind(), inet_bind2_bucket_match_addr_any() returns the tb2 bucket of [::], and inet_bhash2_conflict() finally calls inet_bind_conflict(), which returns true, meaning conflict. inet_bhash2_addr_any_conflict |- inet_bind2_bucket_match_addr_any <-- return [::] bucket `- inet_bhash2_conflict `- __inet_bhash2_conflict <-- checks IPV6_ONLY for AF_INET | but not for v4-mapped-v6 address `- inet_bind_conflict <-- does not check address inet_bind_conflict() does not check socket addresses because __inet_bhash2_conflict() is expected to do so. However, it checks IPV6_V6ONLY attribute only against AF_INET socket, and not for v4-mapped-v6 address. As a result, v4-mapped-v6 address conflicts with v6-only wildcard address. To avoid that, let's add the missing test to use bhash2 for v4-mapped-v6 address. Fixes: 5e07e672412b ("tcp: Use bhash2 for v4-mapped-v6 non-wildcard address.")

2024-03-29selftests/seccomp: Try to fit runtime of benchmark into timeoutMark Brown
The seccomp benchmark runs five scenarios, one calibration run with no seccomp filters enabled then four further runs each adding a filter. The calibration run times itself for 15s and then each additional run executes for the same number of times. Currently the seccomp tests, including the benchmark, run with an extended 120s timeout but this is not sufficient to robustly run the tests on a lot of platforms. Sample timings from some recent runs: Platform Run 1 Run 2 Run 3 Run 4 --------- ----- ----- ----- ----- PowerEdge R200 16.6s 16.6s 31.6s 37.4s BBB (arm) 20.4s 20.4s 54.5s Synquacer (arm64) 20.7s 23.7s 40.3s The x86 runs from the PowerEdge are quite marginal and routinely fail, for the successful run reported here the timed portions of the run are at 117.2s leaving less than 3s of margin which is frequently breached. The added overhead of adding filters on the other platforms is such that there is no prospect of their runs fitting into the 120s timeout, especially on 32 bit arm where there is no BPF JIT. While we could lower the time we calibrate for I'm also already seeing the currently completing runs reporting issues with the per filter overheads not matching expectations: Let's instead raise the timeout to 180s which is only a 50% increase on the current timeout which is itself not *too* large given that there's only two tests in this suite.

2024-03-29selftests/ftrace: Fix event filter target_func selectionMark Rutland
The event filter function test has been failing in our internal test farm: | # not ok 33 event filter function - test event filtering on functions Running the test in verbose mode indicates that this is because the test erroneously determines that kmem_cache_free() is the most common caller of kmem_cache_free(): # # + cut -d: -f3 trace # # + sed s/call_site=([^+]*)+0x.*/1/ # # + sort # # + uniq -c # # + sort # # + tail -n 1 # # + sed s/^[ 0-9]*// # # + target_func=kmem_cache_free ... and as kmem_cache_free() doesn't call itself, setting this as the filter function for kmem_cache_free() results in no hits, and consequently the test fails: # # + grep kmem_cache_free trace # # + grep kmem_cache_free # # + wc -l # # + hitcnt=0 # # + grep kmem_cache_free trace # # + grep -v kmem_cache_free # # + wc -l # # + misscnt=0 # # + [ 0 -eq 0 ] # # + exit_fail This seems to be because the system in question has tasks with ':' in their name (which a number of kernel worker threads have). These show up in the trace, e.g. test:.sh-1299 [004] ..... 2886.040608: kmem_cache_free: call_site=putname+0xa4/0xc8 ptr=000000000f4d22f4 name=names_cache ... and so when we try to extact the call_site with: cut -d: -f3 trace | sed 's/call_site=\([^+]*\)+0x.*/\1/' ... the 'cut' command will extrace the column containing 'kmem_cache_free' rather than the column containing 'call_site=...', and the 'sed' command will leave this unchanged. Consequently, the test will decide to use 'kmem_cache_free' as the filter function, resulting in the failure seen above. Fix this by matching the 'call_site=<func>' part specifically to extract the function name.

syzbot reported a problem in ip6erspan_rcv() [1] Issue is that ip6erspan_rcv() (and erspan_rcv()) no longer make sure erspan_base_hdr is present in skb linear part (skb->head) before getting @ver field from it.

2024-03-29r8169: skip DASH fw status checks when DASH is disabledAtlas Yu
On devices that support DASH, the current code in the "rtl_loop_wait" function raises false alarms when DASH is disabled. This occurs because the function attempts to wait for the DASH firmware to be ready, even though it's not relevant in this case. r8169 0000:0c:00.0 eth0: RTL8168ep/8111ep, 38:7c:76:49:08:d9, XID 502, IRQ 86 r8169 0000:0c:00.0 eth0: jumbo features [frames: 9194 bytes, tx checksumming: ko] r8169 0000:0c:00.0 eth0: DASH disabled ... r8169 0000:0c:00.0 eth0: rtl_ep_ocp_read_cond == 0 (loop: 30, delay: 10000). This patch modifies the driver start/stop functions to skip checking the DASH firmware status when DASH is explicitly disabled. This prevents unnecessary delays and false alarms. The patch has been tested on several ThinkStation P8/PX workstations.

2024-03-29x86/bugs: Fix the SRSO mitigation on Zen3/4Borislav Petkov (AMD)
The original version of the mitigation would patch in the calls to the untraining routines directly. That is, the alternative() in UNTRAIN_RET will patch in the CALL to srso_alias_untrain_ret() directly. However, even if commit e7c25c441e9e ("x86/cpu: Cleanup the untrain mess") meant well in trying to clean up the situation, due to micro- architectural reasons, the untraining routine srso_alias_untrain_ret() must be the target of a CALL instruction and not of a JMP instruction as it is done now. Reshuffle the alternative macros to accomplish that.

2024-03-29net/rds: fix possible cp null dereferenceMahmoud Adam
cp might be null, calling cp->cp_conn would produce null dereference [Simon Horman adds:] Analysis: * cp is a parameter of __rds_rdma_map and is not reassigned. * The following call-sites pass a NULL cp argument to __rds_rdma_map() - rds_get_mr() - rds_get_mr_for_dest * Prior to the code above, the following assumes that cp may be NULL (which is indicative, but could itself be unnecessary) trans_private = rs->rs_transport->get_mr( sg, nents, rs, &mr->r_key, cp ? cp->cp_conn : NULL, args->vec.addr, args->vec.bytes, need_odp ? ODP_ZEROBASED : ODP_NOT_NEEDED); * The code modified by this patch is guarded by IS_ERR(trans_private), where trans_private is assigned as per the previous point in this analysis. The only implementation of get_mr that I could locate is rds_ib_get_mr() which can return an ERR_PTR if the conn (4th) argument is NULL. * ret is set to PTR_ERR(trans_private). rds_ib_get_mr can return ERR_PTR(-ENODEV) if the conn (4th) argument is NULL. Thus ret may be -ENODEV in which case the code in question will execute. Conclusion: * cp may be NULL at the point where this patch adds a check; this patch does seem to address a possible bug Fixes: c055fc00c07b ("net/rds: fix WARNING in rds_conn_connect_if_down") Cc: stable@vger.kernel.org # v4.19+ Signed-off-by: Mahmoud Adam <mngyadam@amazon.com> Reviewed-by: Simon Horman <horms@kernel.org> Link: https://lore.kernel.org/r/20240326153132.55580-1-mngyadam@amazon.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2024-03-29mm: clean up populate_vma_page_range() FOLL_* flag handlingLinus Torvalds
The code wasn't exactly wrong, but it was very odd, and it used FOLL_FORCE together with FOLL_WRITE when it really didn't need to (it only set FOLL_WRITE for writable mappings, so then the FOLL_FORCE was pointless). It also pointlessly called __get_user_pages() even when it knew it wouldn't populate anything because the vma wasn't accessible and it explicitly tested for and did *not* set FOLL_FORCE for inaccessible vma's. This code does need to use FOLL_FORCE, because we want to do fault in writable shared mappings, but then the mapping may not actually be readable. And we don't want to use FOLL_WRITE (which would match the permission of the vma), because that would also dirty the pages, which we don't want to do. For very similar reasons, FOLL_FORCE populates a executable-only mapping with no read permissions. We don't have a FOLL_EXEC flag. Yes, it would probably be cleaner to split FOLL_WRITE into two bits (for separate permission and dirty bit handling), and add a FOLL_EXEC flag for the "GUP executable page" case. That would allow us to avoid FOLL_FORCE entirely here. But that's not how our FOLL_xyz bits have traditionally worked, and that would be a much bigger patch. So this at least avoids the FOLL_FORCE | FOLL_WRITE combination that made one of my experimental validation patches trigger a warning. That warning was a false positive (and my experimental patch was incomplete anyway), but it all made me look at this and decide to clean at least this small case up.

One example of this exception is: Unable to handle kernel NULL pointer dereference at virtual address 0000000000000070 Mem abort info: ESR = 0x0000000096000004 EC = 0x25: DABT (current EL), IL = 32 bits SET = 0, FnV = 0 EA = 0, S1PTW = 0 FSC = 0x04: level 0 translation fault Data abort info: ISV = 0, ISS = 0x00000004 CM = 0, WnR = 0 user pgtable: 4k pages, 48-bit VAs, pgdp=000000011d373000 [0000000000000070] pgd=0000000000000000, p4d=0000000000000000 Internal error: Oops: 96000004 [#1] SMP CPU: 0 PID: 13 Comm: ksoftirqd/0 Tainted: G S OE 5.15.0-bf.6.gef6992a #1 Hardware name: https://www.mellanox.com BlueField SoC/BlueField SoC, BIOS 4.0.2.12669 Apr 21 2023 pstate: 20400009 (nzCv daif +PAN -UAO -TCO -DIT -SSBS BTYPE=--) pc : mlxbf_gige_handle_tx_complete+0xc8/0x170 [mlxbf_gige] lr : mlxbf_gige_poll+0x54/0x160 [mlxbf_gige] sp : ffff8000080d3c10 x29: ffff8000080d3c10 x28: ffffcce72cbb7000 x27: ffff8000080d3d58 x26: ffff0000814e7340 x25: ffff331cd1a05000 x24: ffffcce72c4ea008 x23: ffff0000814e4b40 x22: ffff0000814e4d10 x21: ffff0000814e4128 x20: 0000000000000000 x19: ffff0000814e4a80 x18: ffffffffffffffff x17: 000000000000001c x16: ffffcce72b4553f4 x15: ffff80008805b8a7 x14: 0000000000000000 x13: 0000000000000030 x12: 0101010101010101 x11: 7f7f7f7f7f7f7f7f x10: c2ac898b17576267 x9 : ffffcce720fa5404 x8 : ffff000080812138 x7 : 0000000000002e9a x6 : 0000000000000080 x5 : ffff00008de3b000 x4 : 0000000000000000 x3 : 0000000000000001 x2 : 0000000000000000 x1 : 0000000000000000 x0 : 0000000000000000 Call trace: mlxbf_gige_handle_tx_complete+0xc8/0x170 [mlxbf_gige] mlxbf_gige_poll+0x54/0x160 [mlxbf_gige] __napi_poll+0x40/0x1c8 net_rx_action+0x314/0x3a0 __do_softirq+0x128/0x334 run_ksoftirqd+0x54/0x6c smpboot_thread_fn+0x14c/0x190 kthread+0x10c/0x110 ret_from_fork+0x10/0x20 Code: 8b070000 f9000ea0 f95056c0 f86178a1 (b9407002) ---[ end trace 7cc3941aa0d8e6a4 ]--- Kernel panic - not syncing: Oops: Fatal exception in interrupt Kernel Offset: 0x4ce722520000 from 0xffff800008000000 PHYS_OFFSET: 0x80000000 CPU features: 0x000005c1,a3330e5a Memory Limit: none ---[ end Kernel panic - not syncing: Oops: Fatal exception in interrupt ]--- During system shutdown, the mlxbf_gige driver's shutdown() is always executed. However, the driver's stop() method will only execute if networking interface configuration logic within the Linux distribution has been setup to do so. If shutdown() executes but stop() does not execute, NAPI remains enabled and this can lead to an exception if NAPI is scheduled while the hardware interface has only been partially deinitialized. The networking interface managed by the mlxbf_gige driver must be properly stopped during system shutdown so that IFF_UP is cleared, the hardware interface is put into a clean state, and NAPI is fully deinitialized.
