This test already catches a netlink bug fixed by this series, but only when running on HW with many queues. Make sure the netdevsim instance created has a lot of queues, and constrain the size of the recv_buffer used by netlink. While at it test both rx and tx queues.

2024-12-16selftests: net: support setting recv_size in YNLJakub Kicinski
recv_size parameter allows constraining the buffer size for dumps. It's useful in testing kernel handling of dump continuation, IOW testing dumps which span multiple skbs. Let the tests set this parameter when initializing the YNL family. Keep the normal default, we don't want tests to unintentionally behave very differently than normal code.

2024-12-16fortify: Hide run-time copy size from value range trackingKees Cook
GCC performs value range tracking for variables as a way to provide better diagnostics. One place this is regularly seen is with warnings associated with bounds-checking, e.g. -Wstringop-overflow, -Wstringop-overread, -Warray-bounds, etc. In order to keep the signal-to-noise ratio high, warnings aren't emitted when a value range spans the entire value range representable by a given variable. For example: unsigned int len; char dst[8]; ... memcpy(dst, src, len); If len's value is unknown, it has the full "unsigned int" range of [0, UINT_MAX], and GCC's compile-time bounds checks against memcpy() will be ignored. However, when a code path has been able to narrow the range: if (len > 16) return; memcpy(dst, src, len); Then the range will be updated for the execution path. Above, len is now [0, 16] when reading memcpy(), so depending on other optimizations, we might see a -Wstringop-overflow warning like: error: '__builtin_memcpy' writing between 9 and 16 bytes into region of size 8 [-Werror=stringop-overflow] When building with CONFIG_FORTIFY_SOURCE, the fortified run-time bounds checking can appear to narrow value ranges of lengths for memcpy(), depending on how the compiler constructs the execution paths during optimization passes, due to the checks against the field sizes. For example: if (p_size_field != SIZE_MAX && p_size != p_size_field && p_size_field < size) As intentionally designed, these checks only affect the kernel warnings emitted at run-time and do not block the potentially overflowing memcpy(), so GCC thinks it needs to produce a warning about the resulting value range that might be reaching the memcpy(). We have seen this manifest a few times now, with the most recent being with cpumasks: In function ‘bitmap_copy’, inlined from ‘cpumask_copy’ at ./include/linux/cpumask.h:839:2, inlined from ‘__padata_set_cpumasks’ at kernel/padata.c:730:2: ./include/linux/fortify-string.h:114:33: error: ‘__builtin_memcpy’ reading between 257 and 536870904 bytes from a region of size 256 [-Werror=stringop-overread] 114 | #define __underlying_memcpy __builtin_memcpy | ^ ./include/linux/fortify-string.h:633:9: note: in expansion of macro ‘__underlying_memcpy’ 633 | __underlying_##op(p, q, __fortify_size); \ | ^~~~~~~~~~~~~ ./include/linux/fortify-string.h:678:26: note: in expansion of macro ‘__fortify_memcpy_chk’ 678 | #define memcpy(p, q, s) __fortify_memcpy_chk(p, q, s, \ | ^~~~~~~~~~~~~~~~~~~~ ./include/linux/bitmap.h:259:17: note: in expansion of macro ‘memcpy’ 259 | memcpy(dst, src, len); | ^~~~~~ kernel/padata.c: In function ‘__padata_set_cpumasks’: kernel/padata.c:713:48: note: source object ‘pcpumask’ of size [0, 256] 713 | cpumask_var_t pcpumask, | ~~~~~~~~~~~~~~^~~~~~~~ This warning is _not_ emitted when CONFIG_FORTIFY_SOURCE is disabled, and with the recent -fdiagnostics-details we can confirm the origin of the warning is due to FORTIFY's bounds checking: ../include/linux/bitmap.h:259:17: note: in expansion of macro 'memcpy' 259 | memcpy(dst, src, len); | ^~~~~~ '__padata_set_cpumasks': events 1-2 ../include/linux/fortify-string.h:613:36: 612 | if (p_size_field != SIZE_MAX && | ~~~~~~~~~~~~~~~~~~~~~~~~~~~ 613 | p_size != p_size_field && p_size_field < size) | ~~~~~~~~~~~~~~~~~~~~~~~^~~~~~~~~~~~~~~~~~~~~~ | | | (1) when the condition is evaluated to false | (2) when the condition is evaluated to true '__padata_set_cpumasks': event 3 114 | #define __underlying_memcpy __builtin_memcpy | ^ | | | (3) out of array bounds here Note that the cpumask warning started appearing since bitmap functions were recently marked __always_inline in commit ed8cd2b3bd9f ("bitmap: Switch from inline to __always_inline"), which allowed GCC to gain visibility into the variables as they passed through the FORTIFY implementation. In order to silence these false positives but keep otherwise deterministic compile-time warnings intact, hide the length variable from GCC with OPTIMIZE_HIDE_VAR() before calling the builtin memcpy. Additionally add a comment about why all the macro args have copies with const storage.

2024-12-16hwmon: (tmp513) Fix interpretation of values of Temperature Result and Limit ↵Murad Masimov
Registers The values returned by the driver after processing the contents of the Temperature Result and the Temperature Limit Registers do not correspond to the TMP512/TMP513 specifications. A raw register value is converted to a signed integer value by a sign extension in accordance with the algorithm provided in the specification, but due to the off-by-one error in the sign bit index, the result is incorrect. According to the TMP512 and TMP513 datasheets, the Temperature Result (08h to 0Bh) and Limit (11h to 14h) Registers are 13-bit two's complement integer values, shifted left by 3 bits. The value is scaled by 0.0625 degrees Celsius per bit. E.g., if regval = 1 1110 0111 0000 000, the output should be -25 degrees, but the driver will return +487 degrees.

2024-12-16hwmon: (tmp513) Fix Current Register value interpretationMurad Masimov
The value returned by the driver after processing the contents of the Current Register does not correspond to the TMP512/TMP513 specifications. A raw register value is converted to a signed integer value by a sign extension in accordance with the algorithm provided in the specification, but due to the off-by-one error in the sign bit index, the result is incorrect. Moreover, negative values will be reported as large positive due to missing sign extension from u32 to long. According to the TMP512 and TMP513 datasheets, the Current Register (07h) is a 16-bit two's complement integer value. E.g., if regval = 1000 0011 0000 0000, then the value must be (-32000 * lsb), but the driver will return (33536 * lsb). Fix off-by-one bug, and also cast data->curr_lsb_ua (which is of type u32) to long to prevent incorrect cast for negative values. Found by Linux Verification Center (linuxtesting.org) with SVACE.

2024-12-16hwmon: (tmp513) Fix interpretation of values of Shunt Voltage and Limit ↵Murad Masimov
Registers The values returned by the driver after processing the contents of the Shunt Voltage Register and the Shunt Limit Registers do not correspond to the TMP512/TMP513 specifications. A raw register value is converted to a signed integer value by a sign extension in accordance with the algorithm provided in the specification, but due to the off-by-one error in the sign bit index, the result is incorrect. Moreover, the PGA shift calculated with the tmp51x_get_pga_shift function is relevant only to the Shunt Voltage Register, but is also applied to the Shunt Limit Registers. According to the TMP512 and TMP513 datasheets, the Shunt Voltage Register (04h) is 13 to 16 bit two's complement integer value, depending on the PGA setting. The Shunt Positive (0Ch) and Negative (0Dh) Limit Registers are 16-bit two's complement integer values. Below are some examples: * Shunt Voltage Register If PGA = 8, and regval = 1000 0011 0000 0000, then the decimal value must be -32000, but the value calculated by the driver will be 33536. * Shunt Limit Register If regval = 1000 0011 0000 0000, then the decimal value must be -32000, but the value calculated by the driver will be 768, if PGA = 1.

2024-12-16ceph: improve error handling and short/overflow-read logic in __ceph_sync_read()Alex Markuze
This patch refines the read logic in __ceph_sync_read() to ensure more predictable and efficient behavior in various edge cases. - Return early if the requested read length is zero or if the file size (`i_size`) is zero. - Initialize the index variable (`idx`) where needed and reorder some code to ensure it is always set before use. - Improve error handling by checking for negative return values earlier. - Remove redundant encrypted file checks after failures. Only attempt filesystem-level decryption if the read succeeded. - Simplify leftover calculations to correctly handle cases where the read extends beyond the end of the file or stops short. This can be hit by continuously reading a file while, on another client, we keep truncating and writing new data into it. - This resolves multiple issues caused by integer and consequent buffer overflow (`pages` array being accessed beyond `num_pages`): - https://tracker.ceph.com/issues/67524 - https://tracker.ceph.com/issues/68980 - https://tracker.ceph.com/issues/68981 Cc: stable@vger.kernel.org Fixes: 1065da21e5df ("ceph: stop copying to iter at EOF on sync reads") Reported-by: Luis Henriques (SUSE) <luis.henriques@linux.dev> Signed-off-by: Alex Markuze <amarkuze@redhat.com> Reviewed-by: Viacheslav Dubeyko <Slava.Dubeyko@ibm.com> Signed-off-by: Ilya Dryomov <idryomov@gmail.com>

2024-12-16ftrace: Do not find "true_parent" if HAVE_DYNAMIC_FTRACE_WITH_ARGS is not setSteven Rostedt
When function tracing and function graph tracing are both enabled (in different instances) the "parent" of some of the function tracing events is "return_to_handler" which is the trampoline used by function graph tracing. To fix this, ftrace_get_true_parent_ip() was introduced that returns the "true" parent ip instead of the trampoline. To do this, the ftrace_regs_get_stack_pointer() is used, which uses kernel_stack_pointer(). The problem is that microblaze does not implement kerenl_stack_pointer() so when function graph tracing is enabled, the build fails. But microblaze also does not enabled HAVE_DYNAMIC_FTRACE_WITH_ARGS. That option has to be enabled by the architecture to reliably get the values from the fregs parameter passed in. When that config is not set, the architecture can also pass in NULL, which is not tested for in that function and could cause the kernel to crash.

2024-12-16fgraph: Still initialize idle shadow stacks when startingSteven Rostedt
A bug was discovered where the idle shadow stacks were not initialized for offline CPUs when starting function graph tracer, and when they came online they were not traced due to the missing shadow stack. To fix this, the idle task shadow stack initialization was moved to using the CPU hotplug callbacks. But it removed the initialization when the function graph was enabled. The problem here is that the hotplug callbacks are called when the CPUs come online, but the idle shadow stack initialization only happens if function graph is currently active. This caused the online CPUs to not get their shadow stack initialized. The idle shadow stack initialization still needs to be done when the function graph is registered, as they will not be allocated if function graph is not registered.

2024-12-16PCI/MSI: Handle lack of irqdomain gracefullyThomas Gleixner
Alexandre observed a warning emitted from pci_msi_setup_msi_irqs() on a RISCV platform which does not provide PCI/MSI support: WARNING: CPU: 1 PID: 1 at drivers/pci/msi/msi.h:121 pci_msi_setup_msi_irqs+0x2c/0x32 __pci_enable_msix_range+0x30c/0x596 pci_msi_setup_msi_irqs+0x2c/0x32 pci_alloc_irq_vectors_affinity+0xb8/0xe2 RISCV uses hierarchical interrupt domains and correctly does not implement the legacy fallback. The warning triggers from the legacy fallback stub. That warning is bogus as the PCI/MSI layer knows whether a PCI/MSI parent domain is associated with the device or not. There is a check for MSI-X, which has a legacy assumption. But that legacy fallback assumption is only valid when legacy support is enabled, but otherwise the check should simply return -ENOTSUPP. Loongarch tripped over the same problem and blindly enabled legacy support without implementing the legacy fallbacks. There are weak implementations which return an error, so the problem was papered over. Correct pci_msi_domain_supports() to evaluate the legacy mode and add the missing supported check into the MSI enable path to complete it.

2024-12-16thunderbolt: Improve redrive mode handlingMika Westerberg
When USB-C monitor is connected directly to Intel Barlow Ridge host, it goes into "redrive" mode that basically routes the DisplayPort signals directly from the GPU to the USB-C monitor without any tunneling needed. However, the host router must be powered on for this to work. Aaron reported that there are a couple of cases where this will not work with the current code: - Booting with USB-C monitor plugged in. - Plugging in USB-C monitor when the host router is in sleep state (runtime suspended). - Plugging in USB-C device while the system is in system sleep state. In all these cases once the host router is runtime suspended the picture on the connected USB-C display disappears too. This is certainly not what the user expected. For this reason improve the redrive mode handling to keep the host router from runtime suspending when detect that any of the above cases is happening.

2024-12-15ksmbd: fix broken transfers when exceeding max simultaneous operationsMarios Makassikis
Since commit 0a77d947f599 ("ksmbd: check outstanding simultaneous SMB operations"), ksmbd enforces a maximum number of simultaneous operations for a connection. The problem is that reaching the limit causes ksmbd to close the socket, and the client has no indication that it should have slowed down. This behaviour can be reproduced by setting "smb2 max credits = 128" (or lower), and transferring a large file (25GB). smbclient fails as below: $ smbclient //192.168.1.254/testshare -U user%pass smb: \> put file.bin cli_push returned NT_STATUS_USER_SESSION_DELETED putting file file.bin as \file.bin smb2cli_req_compound_submit: Insufficient credits. 0 available, 1 needed NT_STATUS_INTERNAL_ERROR closing remote file \file.bin smb: \> smb2cli_req_compound_submit: Insufficient credits. 0 available, 1 needed Windows clients fail with 0x8007003b (with smaller files even). Fix this by delaying reading from the socket until there's room to allocate a request. This effectively applies backpressure on the client, so the transfer completes, albeit at a slower rate.

The existing linked list based implementation of how ts tags are assigned and managed is unsafe against concurrency and corner cases: - element addition in tx processing can race against element removal in ts queue completion, - element removal in ts queue completion can race against element removal in device close, - if a large number of frames gets added to tx queue without ts queue completions in between, elements with duplicate tag values can get added. Use a different implementation, based on per-port used tags bitmaps and saved skb arrays.
