2020-04-01NFS: Fix memory leaks in nfs_pageio_stop_mirroring()Trond Myklebust
If we just set the mirror count to 1 without first clearing out the mirrors, we can leak queued up requests. Signed-off-by: Trond Myklebust <trond.myklebust@hammerspace.com>
2020-04-01NFS: Fix a request reference leak in nfs_direct_write_clear_reqs()Trond Myklebust
nfs_direct_write_scan_commit_list() will lock the request and bump the reference count, but we also need to account for the reference that was taken when we initially added the request to the commit list.

2020-04-01NFS: Fix use-after-free issues in nfs_pageio_add_request()Trond Myklebust
We need to ensure that we create the mirror requests before calling nfs_pageio_add_request_mirror() on the request we are adding. Otherwise, we can end up with a use-after-free if the call to nfs_pageio_add_request_mirror() triggers I/O.

2020-04-01NFS: Fix races nfs_page_group_destroy() vs nfs_destroy_unlinked_subrequests()Trond Myklebust

2020-04-01signal: Extend exec_id to 64bitsEric W. Biederman
Replace the 32bit exec_id with a 64bit exec_id to make it impossible to wrap the exec_id counter. With care an attacker can cause exec_id wrap and send arbitrary signals to a newly exec'd parent. This bypasses the signal sending checks if the parent changes their credentials during exec. The severity of this problem can been seen that in my limited testing of a 32bit exec_id it can take as little as 19s to exec 65536 times. Which means that it can take as little as 14 days to wrap a 32bit exec_id. Adam Zabrocki has succeeded wrapping the self_exe_id in 7 days. Even my slower timing is in the uptime of a typical server. Which means self_exec_id is simply a speed bump today, and if exec gets noticably faster self_exec_id won't even be a speed bump. Extending self_exec_id to 64bits introduces a problem on 32bit architectures where reading self_exec_id is no longer atomic and can take two read instructions. Which means that is is possible to hit a window where the read value of exec_id does not match the written value. So with very lucky timing after this change this still remains expoiltable. I have updated the update of exec_id on exec to use WRITE_ONCE and the read of exec_id in do_notify_parent to use READ_ONCE to make it clear that there is no locking between these two locations.

2020-04-01kdb: Censor attempts to set PROMPT without ENABLE_MEM_READDaniel Thompson
Currently the PROMPT variable could be abused to provoke the printf() machinery to read outside the current stack frame. Normally this doesn't matter becaues md is already a much better tool for reading from memory. However the md command can be disabled by not setting KDB_ENABLE_MEM_READ. Let's also prevent PROMPT from being modified in these circumstances. Whilst adding a comment to help future code reviewers we also remove the #ifdef where PROMPT in consumed. There is no problem passing an unused (0) to snprintf when !CONFIG_SMP. argument Reported-by: Wang Xiayang <xywang.sjtu@sjtu.edu.cn> Signed-off-by: Daniel Thompson <daniel.thompson@linaro.org> Reviewed-by: Douglas Anderson <dianders@chromium.org>
2020-04-01kdb: Eliminate strncpy() warnings by replacing with strscpy()Daniel Thompson
Currently the code to manage the kdb history buffer uses strncpy() to copy strings to/and from the history and exhibits the classic "but nobody ever told me that strncpy() doesn't always terminate strings" bug. Modern gcc compilers recognise this bug and issue a warning. In reality these calls will only abridge the copied string if kdb_read() has *already* overflowed the command buffer. Thus the use of counted copies here is only used to reduce the secondary effects of a bug elsewhere in the code. Therefore transitioning these calls into strscpy() (without checking the return code) is appropriate.

2020-04-01powerpc: Make setjmp/longjmp signature standardClement Courbet
Declaring setjmp()/longjmp() as taking longs makes the signature non-standard, and makes clang complain. In the past, this has been worked around by adding -ffreestanding to the compile flags. The implementation looks like it only ever propagates the value (in longjmp) or sets it to 1 (in setjmp), and we only call longjmp with integer parameters. This allows removing -ffreestanding from the compilation flags.

2020-04-01selftests/powerpc: Fix try-run when source tree is not writableMichael Ellerman
We added a usage of try-run to pmu/ebb/Makefile to detect if the toolchain supported the -no-pie option. This fails if we build out-of-tree and the source tree is not writable, as try-run tries to write its temporary files to the current directory. That leads to the -no-pie option being silently dropped, which leads to broken executables with some toolchains. If we remove the redirect to /dev/null in try-run, we see the error: make[3]: Entering directory '/linux/tools/testing/selftests/powerpc/pmu/ebb' /usr/bin/ld: cannot open output file .54.tmp: Read-only file system collect2: error: ld returned 1 exit status make[3]: Nothing to be done for 'all'. And looking with strace we see it's trying to use a file that's in the source tree: lstat("/linux/tools/testing/selftests/powerpc/pmu/ebb/.54.tmp", 0x7ffffc0f83c8) We can fix it by setting TMPOUT to point to the $(OUTPUT) directory, and we can verify with strace it's now trying to write to the output directory: lstat("/output/kselftest/powerpc/pmu/ebb/.54.tmp", 0x7fffd1bf6bf8) And also see that the -no-pie option is now correctly detected.
