2023-07-20llc: Check netns in llc_estab_match() and llc_listener_match().Kuniyuki Iwashima
We will remove this restriction in llc_rcv() in the following patch, which means that the protocol handler must be aware of netns. if (!net_eq(dev_net(dev), &init_net)) goto drop; llc_rcv() fetches llc_type_handlers[llc_pdu_type(skb) - 1] and calls it if not NULL. If the PDU type is LLC_DEST_CONN, llc_conn_handler() is called to pass skb to corresponding sockets. Then, we must look up a proper socket in the same netns with skb->dev. llc_conn_handler() calls __llc_lookup() to look up a established or litening socket by __llc_lookup_established() and llc_lookup_listener(). Both functions iterate on a list and call llc_estab_match() or llc_listener_match() to check if the socket is the correct destination. However, these functions do not check netns. Also, bind() and connect() call llc_establish_connection(), which finally calls __llc_lookup_established(), to check if there is a conflicting socket. Let's test netns in llc_estab_match() and llc_listener_match(). Signed-off-by: Kuniyuki Iwashima <kuniyu@amazon.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2023-07-20llc: Check netns in llc_dgram_match().Kuniyuki Iwashima
We will remove this restriction in llc_rcv() soon, which means that the protocol handler must be aware of netns. if (!net_eq(dev_net(dev), &init_net)) goto drop; llc_rcv() fetches llc_type_handlers[llc_pdu_type(skb) - 1] and calls it if not NULL. If the PDU type is LLC_DEST_SAP, llc_sap_handler() is called to pass skb to corresponding sockets. Then, we must look up a proper socket in the same netns with skb->dev. If the destination is a multicast address, llc_sap_handler() calls llc_sap_mcast(). It calculates a hash based on DSAP and skb->dev->ifindex, iterates on a socket list, and calls llc_mcast_match() to check if the socket is the correct destination. Then, llc_mcast_match() checks if skb->dev matches with llc_sk(sk)->dev. So, we need not check netns here. OTOH, if the destination is a unicast address, llc_sap_handler() calls llc_lookup_dgram() to look up a socket, but it does not check the netns. Therefore, we need to add netns check in llc_lookup_dgram(). Signed-off-by: Kuniyuki Iwashima <kuniyu@amazon.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2023-07-20fbdev: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-07-19Revert "tcp: avoid the lookup process failing to get sk in ehash table"Kuniyuki Iwashima
This reverts commit 3f4ca5fafc08881d7a57daa20449d171f2887043. Commit 3f4ca5fafc08 ("tcp: avoid the lookup process failing to get sk in ehash table") reversed the order in how a socket is inserted into ehash to fix an issue that ehash-lookup could fail when reqsk/full sk/twsk are swapped. However, it introduced another lookup failure. The full socket in ehash is allocated from a slab with SLAB_TYPESAFE_BY_RCU and does not have SOCK_RCU_FREE, so the socket could be reused even while it is being referenced on another CPU doing RCU lookup. Let's say a socket is reused and inserted into the same hash bucket during lookup. After the blamed commit, a new socket is inserted at the end of the list. If that happens, we will skip sockets placed after the previous position of the reused socket, resulting in ehash lookup failure. As described in Documentation/RCU/rculist_nulls.rst, we should insert a new socket at the head of the list to avoid such an issue. This issue, the swap-lookup-failure, and another variant reported in [0] can all be handled properly by adding a locked ehash lookup suggested by Eric Dumazet [1]. However, this issue could occur for every packet, thus more likely than the other two races, so let's revert the change for now.

2023-07-19x86/speculation: Add Gather Data Sampling mitigationDaniel Sneddon
Gather Data Sampling (GDS) is a hardware vulnerability which allows unprivileged speculative access to data which was previously stored in vector registers. Intel processors that support AVX2 and AVX512 have gather instructions that fetch non-contiguous data elements from memory. On vulnerable hardware, when a gather instruction is transiently executed and encounters a fault, stale data from architectural or internal vector registers may get transiently stored to the destination vector register allowing an attacker to infer the stale data using typical side channel techniques like cache timing attacks. This mitigation is different from many earlier ones for two reasons. First, it is enabled by default and a bit must be set to *DISABLE* it. This is the opposite of normal mitigation polarity. This means GDS can be mitigated simply by updating microcode and leaving the new control bit alone. Second, GDS has a "lock" bit. This lock bit is there because the mitigation affects the hardware security features KeyLocker and SGX. It needs to be enabled and *STAY* enabled for these features to be mitigated against GDS. The mitigation is enabled in the microcode by default. Disable it by setting gather_data_sampling=off or by disabling all mitigations with mitigations=off. The mitigation status can be checked by reading: /sys/devices/system/cpu/vulnerabilities/gather_data_sampling Signed-off-by: Daniel Sneddon <daniel.sneddon@linux.intel.com> Signed-off-by: Dave Hansen <dave.hansen@linux.intel.com> Acked-by: Josh Poimboeuf <jpoimboe@kernel.org>

2023-07-19clk: mediatek: mt8183: Add back SSPM related clocksChen-Yu Tsai
This reverts commit 860690a93ef23b567f781c1b631623e27190f101. On the MT8183, the SSPM related clocks were removed claiming a lack of usage. This however causes some issues when the driver was converted to the new simple-probe mechanism. This mechanism allocates enough space for all the clocks defined in the clock driver, not the highest index in the DT binding. This leads to out-of-bound writes if their are holes in the DT binding or the driver (due to deprecated or unimplemented clocks). These errors can go unnoticed and cause memory corruption, leading to crashes in unrelated areas, or nothing at all. KASAN will detect them. Add the SSPM related clocks back to the MT8183 clock driver to fully implement the DT binding. The SSPM clocks are for the power management co-processor, and should never be turned off. They are marked as such.

2023-07-19KVM: arm64: Allow pKVM on v1.0 compatible FF-A implementationsOliver Upton
pKVM initialization fails on systems with v1.1+ FF-A implementations, as the hyp does a strict match on the returned version from FFA_VERSION. This is a stronger assertion than required by the specification, which requires minor revisions be backwards compatible with earlier revisions of the same major version. Relax the check in hyp_ffa_init() to only test the returned major version. Even though v1.1 broke ABI, the expectation is that firmware incapable of using the v1.0 ABI return NOT_SUPPORTED instead of a valid version.

2023-07-19regcache: Push async I/O request down into the rbtree cacheMark Brown
Currently the regcache core unconditionally enables async I/O for all cache types, causing problems for the maple tree cache which dynamically allocates the buffers used to write registers to the device since async requires the buffers to be kept around until the I/O has been completed. This use of async I/O is mainly for the rbtree cache which stores data in a format directly usable for regmap_raw_write(), though there is a special case for single register writes which would also have allowed it to be used with the flat cache. It is a bit of a landmine for other caches since it implicitly converts sync operations to async, and with modern hardware it is not clear that async I/O is actually a performance win as shown by the performance work David Jander did with SPI. In multi core systems the cost of managing concurrency ends up swamping the performance benefit and almost all modern systems are multi core. Address this by pushing the enablement of async I/O down into the rbtree cache where it is actively used, avoiding surprises for other cache implementations.

2023-07-19Revert "powerpc/64s: Remove support for ELFv1 little endian userspace"Andrew Donnellan
This reverts commit 606787fed7268feb256957872586370b56af697a. ELFv1 with LE has never been a thing, and people who try to make ELFv1 LE binaries are maniacs who need to be stopped, but unfortunately there are ELFv1 LE binaries out there in the wild. One such binary is the ppc64el (as Debian calls it) helper for arch-test[0], a tool for detecting architectures that can be executed on a given machine by means of attempting to execute helper binaries compiled for each architecture and seeing which binaries succeed and fail. The helpers are small snippets of assembly, and the ppc64el assembly doesn't include the right directives to generate an ELFv2 binary. This results in arch-test incorrectly determining that a ppc64el kernel can't execute a ppc64el userspace, which in turn means that a number of developer tools such as debootstrap will break (assuming arch-test is installed).

The blk-ctrl device is deliberately placed outside of the GPC power domain as it needs to control the power sequencing of the blk-ctrl domains together with the GPC domains. Clock runtime PM works by operating on the clock parent device, which doesn't translate into the neccessary GPC power domain action if the clk parent is not part of the GPC power domain. Use the bus_power_device as the parent for the clock to trigger the proper GPC domain actions on clock runtime power management.
