* Update copyright dates with scripts/update-copyrightsPaul Eggert2022-01-011-1/+1
| | | | | | | | | | | | | | | | | | | | | | | I used these shell commands: ../glibc/scripts/update-copyrights $PWD/../gnulib/build-aux/update-copyright (cd ../glibc && git commit -am"[this commit message]") and then ignored the output, which consisted lines saying "FOO: warning: copyright statement not found" for each of 7061 files FOO. I then removed trailing white space from math/tgmath.h, support/tst-support-open-dev-null-range.c, and sysdeps/x86_64/multiarch/strlen-vec.S, to work around the following obscure pre-commit check failure diagnostics from Savannah. I don't know why I run into these diagnostics whereas others evidently do not. remote: *** 912-#endif remote: *** 913: remote: *** 914- remote: *** error: lines with trailing whitespace found ... remote: *** error: sysdeps/unix/sysv/linux/statx_cp.c: trailing lines

* aarch64: Add sysv specific enabling code for memory taggingRichard Earnshaw2020-12-211-0/+1
| | | | | | | | | | | | | | | | | | | Add various defines and stubs for enabling MTE on AArch64 sysv-like systems such as Linux. The HWCAP feature bit is copied over in the same way as other feature bits. Similarly we add a new wrapper header for mman.h to define the PROT_MTE flag that can be used with mmap and related functions. We add a new field to struct cpu_features that can be used, for example, to check whether or not certain ifunc'd routines should be bound to MTE-safe versions. Finally, if we detect that MTE should be enabled (ie via the glibc tunable); we enable MTE during startup as required. Support in the Linux kernel was added in version 5.10.

* aarch64: enable BTI at runtimeSudakshina Das2020-07-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Binaries can opt-in to using BTI via an ELF object file marking. The dynamic linker has to then mprotect the executable segments with PROT_BTI. In case of static linked executables or in case of the dynamic linker itself, PROT_BTI protection is done by the operating system. On AArch64 glibc uses PT_GNU_PROPERTY instead of PT_NOTE to check the properties of a binary because PT_NOTE can be unreliable with old linkers (old linkers just append the notes of input objects together and add them to the output without checking them for consistency which means multiple incompatible GNU property notes can be present in PT_NOTE). BTI property is handled in the loader even if glibc is not built with BTI support, so in theory user code can be BTI protected independently of glibc. In practice though user binaries are not marked with the BTI property if glibc has no support because the static linked libc objects (crt files, libc_nonshared.a) are unmarked. This patch relies on Linux userspace API that is not yet in a linux release but in v5.8-rc1 so scheduled to be in Linux 5.8.
