[PATCH] iscsi-target: fix hang in iscsit_access_np() when getting tpg->np_login_sem

by Hou Pu

The iscsi target login thread might stuck in following stack: cat /proc/`pidof iscsi_np`/stack [<0>] down_interruptible+0x42/0x50 [<0>] iscsit_access_np+0xe3/0x167 [<0>] iscsi_target_locate_portal+0x695/0x8ac [<0>] __iscsi_target_login_thread+0x855/0xb82 [<0>] iscsi_target_login_thread+0x2f/0x5a [<0>] kthread+0xfa/0x130 [<0>] ret_from_fork+0x1f/0x30 This could be reproduced by following steps: 1. Initiator A try to login iqn1-tpg1 on port 3260. After finishing PDU exchange in the login thread and before the negotiation is finished, at this time the network link is down. In a production environment, this could happen. I could emulated it by bring the network card down in the initiator node by ifconfig eth0 down. (Now A could never finish this login. And tpg->np_login_sem is hold by it). 2. Initiator B try to login iqn2-tpg1 on port 3260. After finishing PDU exchange in the login thread. The target expect to process remaining login PDUs in workqueue context. 3. Initiator A' try to re-login to iqn1-tpg1 on port 3260 from a new socket. It will wait for tpg->np_login_sem with np->np_login_timer loaded to wait for at most 15 second. (Because the lock is held by A. A never gets a change to release tpg->np_login_sem. so A' should finally get timeout). 4. Before A' got timeout. Initiator B gets negotiation failed and calls iscsi_target_login_drop()->iscsi_target_login_sess_out(). The np->np_login_timer is canceled. And initiator A' will hang there forever. Because A' is now in the login thread. All other login requests could not be serviced. Fix this by moving iscsi_stop_login_thread_timer() out of iscsi_target_login_sess_out(). Also remove iscsi_np parameter from iscsi_target_login_sess_out().

[PATCH] Makefile: add -fuse-ld=lld to KBUILD_HOSTLDFLAGS when LLVM=1

by Nick Desaulniers

While moving Android kernels over to use LLVM=1, we observe the failure when building in a hermetic docker image: HOSTCC scripts/basic/fixdep clang: error: unable to execute command: Executable "ld" doesn't exist! The is because the build of the host utility fixdep builds the fixdep executable in one step by invoking the compiler as the driver, rather than individual compile then link steps. Clang when configured from source defaults to use the system's linker, and not LLVM's own LLD, unless the CMake config -DCLANG_DEFAULT_LINKER='lld' is set when configuring a build of clang itself. Don't rely on the compiler's implicit default linker; be explicit.

[PATCH V2] block: allow for_each_bvec to support zero len bvec

by Ming Lei

Block layer usually doesn't support or allow zero-length bvec. Since commit 1bdc76aea115 ("iov_iter: use bvec iterator to implement iterate_bvec()"), iterate_bvec() switches to bvec iterator. However, Al mentioned that 'Zero-length segments are not disallowed' in iov_iter. Fixes for_each_bvec() so that it can move on after seeing one zero length bvec.

[PATCH] x86/special_insn: reverse __force_order logic

by Nadav Amit

From: Nadav Amit <namit(a)vmware.com> The __force_order logic seems to be inverted. __force_order is supposedly used to manipulate the compiler to use its memory dependencies analysis to enforce orders between CR writes and reads. Therefore, the memory should behave as a "CR": when the CR is read, the memory should be "read" by the inline assembly, and __force_order should be an output. When the CR is written, the memory should be "written". This change should allow to remove the "volatile" qualifier from CR reads at a later patch. While at it, remove the extra new-line from the inline assembly, as it only confuses GCC when it estimates the cost of the inline assembly.

Shouldn't this have a CC stable tag and a fixes tag on it? AFAICS this is a fix for a UAF that exists since f3bd9dae3708a0ff6b067e766073ffeb853301f9 ("io_uring: fix memleak in __io_sqe_files_update()"), and that commit was marked for stable backporting back to when c3a31e605620 landed, and that commit was introduced in Linux 5.5. You can see at <https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/tree/fs/io…> that this security vulnerability currently exists in the stable 5.8 branch.
