[PATCH v3] powerpc/bpf: fix JIT code size calculation of bpf trampoline

by Hari Bathini

arch_bpf_trampoline_size() provides JIT size of the BPF trampoline before the buffer for JIT'ing it is allocated. The total number of instructions emitted for BPF trampoline JIT code depends on where the final image is located. So, the size arrived at with the dummy pass in arch_bpf_trampoline_size() can vary from the actual size needed in arch_prepare_bpf_trampoline(). When the instructions accounted in arch_bpf_trampoline_size() is less than the number of instructions emitted during the actual JIT compile of the trampoline, the below warning is produced: WARNING: CPU: 8 PID: 204190 at arch/powerpc/net/bpf_jit_comp.c:981 __arch_prepare_bpf_trampoline.isra.0+0xd2c/0xdcc which is: /* Make sure the trampoline generation logic doesn't overflow */ if (image && WARN_ON_ONCE(&image[ctx->idx] > (u32 *)rw_image_end - BPF_INSN_SAFETY)) { So, during the dummy pass, instead of providing some arbitrary image location, account for maximum possible instructions if and when there is a dependency with image location for JIT'ing.

[PATCH 6.1 6.6 6.12 6.13] scripts/sorttable: fix ELF64 mcount_loc address parsing when compiling on 32-bit

by Sahil Gupta

The ftrace __mcount_loc buildtime sort does not work properly when the host is 32-bit and the target is 64-bit. sorttable parses the start and stop addresses by calling strtoul on the buffer holding the hexadecimal string. Since the target is 64-bit but unsigned long on 32-bit machines is 32 bits, strtoul, and by extension the start and stop addresses, can max out to 2^32 - 1. This patch adds a new macro, parse_addr, that corresponds to a strtoul or strtoull call based on whether you are operating on a 32-bit ELF or a 64-bit ELF. This way, the correct width is guaranteed whether or not the host is 32-bit. This should cleanly apply on all of the 6.x stable kernels. Manually verified that the __mcount_loc section is sorted by parsing the ELF and verified tests corresponding to CONFIG_FTRACE_SORT_STARTUP_TEST for kernels built on a 32-bit and a 64-bit host.

[PATCH v2] drm/v3d: Add job to pending list if the reset was skipped

by Maíra Canal

When a CL/CSD job times out, we check if the GPU has made any progress since the last timeout. If so, instead of resetting the hardware, we skip the reset and let the timer get rearmed. This gives long-running jobs a chance to complete. However, when `timedout_job()` is called, the job in question is removed from the pending list, which means it won't be automatically freed through `free_job()`. Consequently, when we skip the reset and keep the job running, the job won't be freed when it finally completes. This situation leads to a memory leak, as exposed in [1] and [2]. Similarly to commit 704d3d60fec4 ("drm/etnaviv: don't block scheduler when GPU is still active"), this patch ensures the job is put back on the pending list when extending the timeout.

[PATCH v3] x86/sev: Fix making shared pages private during kdump

by Ashish Kalra

From: Ashish Kalra <ashish.kalra(a)amd.com> When the shared pages are being made private during kdump preparation there are additional checks to handle shared GHCB pages. These additional checks include handling the case of GHCB page being contained within a huge page. While handling the case of GHCB page contained within a huge page any shared page just below the GHCB page gets skipped from being transitioned back to private during kdump preparation. This subsequently causes a 0x404 #VC exception when this skipped shared page is accessed later while dumping guest memory during vmcore generation via kdump. Split the initial check for skipping the GHCB page into the page being skipped fully containing the GHCB and GHCB being contained within a huge page. Also ensure that the skipped huge page containing the GHCB page is transitioned back to private later when changing GHCBs to private at end of kdump preparation.

From: Ashish Kalra <ashish.kalra(a)amd.com> When kdump is running makedumpfile to generate vmcore and dumping SNP guest memory it touches the VMSA page of the vCPU executing kdump which then results in unrecoverable #NPF/RMP faults as the VMSA page is marked busy/in-use when the vCPU is running and subsequently causes guest softlockup/hang. Additionally other APs may be halted in guest mode and their VMSA pages are marked busy and touching these VMSA pages during guest memory dump will also cause #NPF. Issue AP_DESTROY GHCB calls on other APs to ensure they are kicked out of guest mode and then clear the VMSA bit on their VMSA pages. If the vCPU running kdump is an AP, mark it's VMSA page as offline to ensure that makedumpfile excludes that page while dumping guest memory.

[PATCH] fs/eventpoll: fix endless busy loop after timeout has expired

by Max Kellermann

After commit 0a65bc27bd64 ("eventpoll: Set epoll timeout if it's in the future"), the following program would immediately enter a busy loop in the kernel: ``` int main() { int e = epoll_create1(0); struct epoll_event event = {.events = EPOLLIN}; epoll_ctl(e, EPOLL_CTL_ADD, 0, &event); const struct timespec timeout = {.tv_nsec = 1}; epoll_pwait2(e, &event, 1, &timeout, 0); } ``` This happens because the given (non-zero) timeout of 1 nanosecond usually expires before ep_poll() is entered and then ep_schedule_timeout() returns false, but `timed_out` is never set because the code line that sets it is skipped. This quickly turns into a soft lockup, RCU stalls and deadlocks, inflicting severe headaches to the whole system. When the timeout has expired, we don't need to schedule a hrtimer, but we should set the `timed_out` variable. Therefore, I suggest moving the ep_schedule_timeout() check into the `timed_out` expression instead of skipping it.
