The patch below does not apply to the 5.9-stable tree. If someone wants it applied there, or to any other stable or longterm tree, then please email the backport, including the original git commit id to <stable(a)vger.kernel.org>. thanks, greg k-h ------------------ original commit in Linus's tree ------------------ >From f5449e74802c1112dea984aec8af7a33c4516af1 Mon Sep 17 00:00:00 2001 From: Jason Gunthorpe <jgg(a)ziepe.ca> Date: Mon, 14 Sep 2020 08:59:56 -0300 Subject: [PATCH] RDMA/ucma: Rework ucma_migrate_id() to avoid races with destroy ucma_destroy_id() assumes that all things accessing the ctx will do so via the xarray. This assumption violated only in the case the FD is being closed, then the ctx is reached via the ctx_list. Normally this is OK since ucma_destroy_id() cannot run concurrenty with release(), however with ucma_migrate_id() is involved this can violated as the close of the 2nd FD can run concurrently with destroy on the first: CPU0 CPU1 ucma_destroy_id(fda) ucma_migrate_id(fda -> fdb) ucma_get_ctx() xa_lock() _ucma_find_context() xa_erase() xa_unlock() xa_lock() ctx->file = new_file list_move() xa_unlock() ucma_put_ctx() ucma_close(fdb) _destroy_id() kfree(ctx) _destroy_id() wait_for_completion() // boom, ctx was freed The ctx->file must be modified under the handler and xa_lock, and prior to modification the ID must be rechecked that it is still reachable from cur_file, ie there is no parallel destroy or migrate. To make this work remove the double locking and streamline the control flow. The double locking was obsoleted by the handler lock now directly preventing new uevents from being created, and the ctx_list cannot be read while holding fgets on both files. Removing the double locking also removes the need to check for the same file.

[PATCH] staging: comedi: cb_pcidas: reinstate delay removed from trimpot setting

by Ian Abbott

Commit eddd2a4c675c ("staging: comedi: cb_pcidas: refactor write_calibration_bitstream()") inadvertently removed one of the `udelay(1)` calls when writing to the calibration register in `cb_pcidas_calib_write()`. Reinstate the delay. It may seem strange that the delay is placed before the register write, but this function is called in a loop so the extra delay can make a difference. This _might_ solve reported issues reading analog inputs on a PCIe-DAS1602/16 card where the analog input values "were scaled in a strange way that didn't make sense". On the same hardware running a system with a 3.13 kernel, and then a system with a 4.4 kernel, but with the same application software, the system with the 3.13 kernel was fine, but the one with the 4.4 kernel exhibited the problem. Of the 90 changes to the driver between those kernel versions, this change looked like the most likely culprit.

[PATCH v3] RISC-V: Fix the VDSO symbol generaton for binutils-2.35+

by Palmer Dabbelt

We were relying on GNU ld's ability to re-link executable files in order to extract our VDSO symbols. This behavior was deemed a bug as of binutils-2.35 (specifically the binutils-gdb commit a87e1817a4 ("Have the linker fail if any attempt to link in an executable is made."), but as that has been backported to at least Debian's binutils-2.34 in may manifest in other places. The previous version of this was a bit of a mess: we were linking a static executable version of the VDSO, containing only a subset of the input symbols, which we then linked into the kernel. This worked, but certainly wasn't a supported path through the toolchain. Instead this new version parses the textual output of nm to produce a symbol table. Both rely on near-zero addresses being linkable, but as we rely on weak undefined symbols being linkable elsewhere I don't view this as a major issue.

[PATCH] crypto: af_alg - avoid undefined behavior accessing salg_name

by Eric Biggers

From: Eric Biggers <ebiggers(a)google.com> Commit 3f69cc60768b ("crypto: af_alg - Allow arbitrarily long algorithm names") made the kernel start accepting arbitrarily long algorithm names in sockaddr_alg. However, the actual length of the salg_name field stayed at the original 64 bytes. This is broken because the kernel can access indices >= 64 in salg_name, which is undefined behavior -- even though the memory that is accessed is still located within the sockaddr structure. It would only be defined behavior if the array were properly marked as arbitrary-length (either by making it a flexible array, which is the recommended way these days, or by making it an array of length 0 or 1). We can't simply change salg_name into a flexible array, since that would break source compatibility with userspace programs that embed sockaddr_alg into another struct, or (more commonly) declare a sockaddr_alg like 'struct sockaddr_alg sa = { .salg_name = "foo" };'. One solution would be to change salg_name into a flexible array only when '#ifdef __KERNEL__'. However, that would keep userspace without an easy way to actually use the longer algorithm names. Instead, add a new structure 'sockaddr_alg_new' that has the flexible array field, and expose it to both userspace and the kernel. Make the kernel use it correctly in alg_bind(). This addresses the syzbot report "UBSAN: array-index-out-of-bounds in alg_bind" (https://syzkaller.appspot.com/bug?extid=92ead4eb8e26a26d465e).
