Thanks, Sasha ------------------ original commit in Linus's tree ------------------ From b5413156bad91dc2995a5c4eab1b05e56914638a Mon Sep 17 00:00:00 2001 From: Benjamin Segall <bsegall(a)google.com> Date: Fri, 25 Oct 2024 18:35:35 -0700 Subject: [PATCH] posix-cpu-timers: Clear TICK_DEP_BIT_POSIX_TIMER on clone When cloning a new thread, its posix_cputimers are not inherited, and are cleared by posix_cputimers_init(). However, this does not clear the tick dependency it creates in tsk->tick_dep_mask, and the handler does not reach the code to clear the dependency if there were no timers to begin with. Thus if a thread has a cputimer running before clone/fork, all descendants will prevent nohz_full unless they create a cputimer of their own. Fix this by entirely clearing the tick_dep_mask in copy_process(). (There is currently no inherited state that needs a tick dependency) Process-wide timers do not have this problem because fork does not copy signal_struct as a baseline, it creates one from scratch.

[PATCH 2/9] serial: sh-sci: Check if TX data was written to device in .tx_empty()

by Claudiu

From: Claudiu Beznea <claudiu.beznea.uj(a)bp.renesas.com> On the Renesas RZ/G3S, when doing suspend to RAM, the uart_suspend_port() is called. The uart_suspend_port() calls 3 times the struct uart_port::ops::tx_empty() before shutting down the port. According to the documentation, the struct uart_port::ops::tx_empty() API tests whether the transmitter FIFO and shifter for the port is empty. The Renesas RZ/G3S SCIFA IP reports the number of data units stored in the transmit FIFO through the FDR (FIFO Data Count Register). The data units in the FIFOs are written in the shift register and transmitted from there. The TEND bit in the Serial Status Register reports if the data was transmitted from the shift register. In the previous code, in the tx_empty() API implemented by the sh-sci driver, it is considered that the TX is empty if the hardware reports the TEND bit set and the number of data units in the FIFO is zero. According to the HW manual, the TEND bit has the following meaning: 0: Transmission is in the waiting state or in progress. 1: Transmission is completed. It has been noticed that when opening the serial device w/o using it and then switch to a power saving mode, the tx_empty() call in the uart_port_suspend() function fails, leading to the "Unable to drain transmitter" message being printed on the console. This is because the TEND=0 if nothing has been transmitted and the FIFOs are empty. As the TEND=0 has double meaning (waiting state, in progress) we can't determined the scenario described above. Add a software workaround for this. This sets a variable if any data has been sent on the serial console (when using PIO) or if the DMA callback has been called (meaning something has been transmitted). Fixes: 73a19e4c0301 ("serial: sh-sci: Add DMA support.")

[PATCH] media: videobuf2-core: copy vb planes unconditionally

by Tudor Ambarus

Copy the relevant data from userspace to the vb->planes unconditionally as it's possible some of the fields may have changed after the buffer has been validated. Keep the dma_buf_put(planes[plane].dbuf) calls in the first `if (!reacquired)` case, in order to be close to the plane validation code where the buffers were got in the first place.

[PATCH v2 0/2] powerpc: Prepare for clang's per-task stack protector support

by Nathan Chancellor

This series prepares the powerpc Kconfig and Kbuild files for clang's per-task stack protector support. clang requires '-mstack-protector-guard-offset' to always be passed with the other '-mstack-protector-guard' flags, which does not always happen with the powerpc implementation, unlike arm, arm64, and riscv implementations. This series brings powerpc in line with those other architectures, which allows clang's support to work right away when it is merged. Additionally, there is one other fix needed for the Kconfig test to work correctly when targeting 32-bit. I have tested this series in QEMU against LKDTM's REPORT_STACK_CANARY with ppc64le_guest_defconfig and pmac32_defconfig built with a toolchain that contains Keith's in-progress pull request, which should land for LLVM 20: https://github.com/llvm/llvm-project/pull/110928 --- Changes in v2: - Combined patch 1 and 3, as they are fixing the same test for similar reasons; adjust commit message accordingly (Christophe) - Moved stack protector guard flags on one line in Makefile (Christophe) - Add 'Cc: stable' targeting 6.1 and newer for the sake of simplicity, as it is the oldest stable release where this series applies cleanly (folks who want it on earlier releases can request or perform a backport separately). - Pick up Keith's Reviewed-by and Tested-by on both patches. - Add a blurb to commit message of patch 1 explaining why clang's register selection behavior differs from GCC. - Link to v1: https://lore.kernel.org/r/20241007-powerpc-fix-stackprotector-test-clang-v1… --- Nathan Chancellor (2): powerpc: Fix stack protector Kconfig test for clang powerpc: Adjust adding stack protector flags to KBUILD_CLAGS for clang arch/powerpc/Kconfig | 4 ++-- arch/powerpc/Makefile | 13 ++++--------- 2 files changed, 6 insertions(+), 11 deletions(-) --- base-commit: 8cf0b93919e13d1e8d4466eb4080a4c4d9d66d7b change-id: 20241004-powerpc-fix-stackprotector-test-clang-84e67ed82f62 Best regards, -- Nathan Chancellor <nathan(a)kernel.org>

[for 6.11 PATCH] RISC-V: disallow gcc + rust builds

by Conor Dooley

From: Conor Dooley <conor.dooley(a)microchip.com> commit 33549fcf37ec461f398f0a41e1c9948be2e5aca4 upstream During the discussion before supporting rust on riscv, it was decided not to support gcc yet, due to differences in extension handling compared to llvm (only the version of libclang matching the c compiler is supported). Recently Jason Montleon reported [1] that building with gcc caused build issues, due to unsupported arguments being passed to libclang. After some discussion between myself and Miguel, it is better to disable gcc + rust builds to match the original intent, and subsequently support it when an appropriate set of extensions can be deduced from the version of libclang.

[PATCH net 0/6] Make TCP-MD5-diag slightly less broken

by Dmitry Safonov via B4 Relay

My original intent was to replace the last non-upstream Arista's TCP-AO piece. That is per-netns procfs seqfile which lists AO keys. In my view an acceptable upstream alternative would be TCP-AO-diag uAPI. So, I started by looking and reviewing TCP-MD5-diag code. And straight away I saw a bunch of issues: 1. Similarly to TCP_MD5SIG_EXT, which doesn't check tcpm_flags for unknown flags and so being non-extendable setsockopt(), the same way tcp_diag_put_md5sig() dumps md5 keys in an array of tcp_diag_md5sig, which makes it ABI non-extendable structure as userspace can't tolerate any new members in it. 2. Inet-diag allocates netlink message for sockets in inet_diag_dump_one_icsk(), which uses a TCP-diag callback .idiag_get_aux_size(), that pre-calculates the needed space for TCP-diag related information. But as neither socket lock nor rcu_readlock() are held between allocation and the actual TCP info filling, the TCP-related space requirement may change before reaching tcp_diag_put_md5sig(). I.e., the number of TCP-MD5 keys on a socket. Thankfully, TCP-MD5-diag won't overwrite the skb, but will return EMSGSIZE, triggering WARN_ON() in inet_diag_dump_one_icsk(). 3. Inet-diag "do" request* can create skb of any message required size. But "dump" request* the skb size, since d35c99ff77ec ("netlink: do not enter direct reclaim from netlink_dump()") is limited by 32 KB. Having in mind that sizeof(struct tcp_diag_md5sig) = 100 bytes, dumps for sockets that have more than 327 keys are going to fail (not counting other diag infos, which lower this limit futher). That is much lower than the number of TCP-MD5 keys that can be allocated on a socket with the current default optmem_max limit (128Kb). So, then I went and written selftests for TCP-MD5-diag and besides confirming that (2) and (3) are not theoretical issues, I also discovered another issues, that I didn't notice on code inspection: 4. nlattr::nla_len is __u16, which limits the largest netlink attibute by 64Kb or by 655 tcp_diag_md5sig keys in the diag array. What happens de-facto is that the netlink attribute gets u16 overflow, breaking the userspace parsing - RTA_NEXT(), that should point to the next attribute, points into the middle of md5 keys array. In this patch set issues (2) and (4) are addressed. (2) by not returning EMSGSIZE when the dump raced with modifying TCP-MD5 keys on a socket, but mark the dump inconsistent by setting NLM_F_DUMP_INTR nlmsg flag. Which changes uAPI in situations where previously kernel did WARN() and errored the dump. (4) by artificially limiting the maximum attribute size by U16_MAX - 1. In order to remove the new limit from (4) solution, my plan is to convert the dump of TCP-MD5 keys from an array to NL_ATTR_TYPE_NESTED_ARRAY (or alike), which should also address (1). And for (3), it's needed to teach tcp-diag how-to remember not only socket on which previous recvmsg() stopped, but potentially TCP-MD5 key as well. I plan in the next part of patch set address (3), (1) and the new limit for (4), together with adding new TCP-AO-diag. * Terminology from Documentation/userspace-api/netlink/intro.rst Signed-off-by: Dmitry Safonov <0x7f454c46(a)gmail.com> --- Dmitry Safonov (6): net/diag: Do not race on dumping MD5 keys with adding new MD5 keys net/diag: Warn only once on EMSGSIZE net/diag: Pre-allocate optional info only if requested net/diag: Always pre-allocate tcp_ulp info net/diag: Limit TCP-MD5-diag array by max attribute length net/netlink: Correct the comment on netlink message max cap include/linux/inet_diag.h | 3 +- include/net/tcp.h | 1 - net/ipv4/inet_diag.c | 87 ++++++++++++++++++++++++++++++++++++++--------- net/ipv4/tcp_diag.c | 69 ++++++++++++++++++------------------- net/mptcp/diag.c | 20 ----------- net/netlink/af_netlink.c | 4 +-- net/tls/tls_main.c | 17 --------- 7 files changed, 109 insertions(+), 92 deletions(-) --- base-commit: 2e1b3cc9d7f790145a80cb705b168f05dab65df2 change-id: 20241106-tcp-md5-diag-prep-2f0dcf371d90 Best regards, -- Dmitry Safonov <0x7f454c46(a)gmail.com>

[PATCH] irqchip/gic-v3: Force propagation of the active state with a read-back

by Marc Zyngier

Christoffer reports that on some implementations, writing to GICR_ISACTIVER0 (and similar GICD registers) can race badly with a guest issuing a deactivation of that interrupt via the system register interface. There are multiple reasons to this: - we use an early write-acknoledgement memory type (nGnRE), meaning that the write may only have made it as far as some interconnect by the time the store is considered "done" - the GIC itself is allowed to buffer the write until it decides to take it into account (as long as it is in finite time) The effects are that the activation may not have taken effect by the time we enter the guest, forcing an immediate exit, or that a guest deactivation occurs before the interrupt is active, doing nothing. In order to guarantee that the write to the ISACTIVER register has taken effect, read back from it, forcing the interconnect to propagate the write, and the GIC to process the write before returning the read.

[PATCH] arm64/ptrace: Zero FPMR on streaming mode entry/exit

by Mark Brown

When FPMR and SME are both present then entering and exiting streaming mode clears FPMR in the same manner as it clears the V/Z and P registers. Since entering and exiting streaming mode via ptrace is expected to have the same effect as doing so via SMSTART/SMSTOP it should clear FPMR too but this was missed when FPMR support was added. Add the required reset of FPMR. Since changing the vector length resets SVCR a SME vector length change implemented via a write to ZA can trigger an exit of streaming mode and we need to check when writing to ZA as well.
