* aarch64: update NEWS about branch protectionSzabolcs Nagy2020-08-031-1/+3
| | | | | | | | | | | After some discussions it seems the original news was not clear and that it is valid to manually pass the branch protection flags iff GCC target libs are built with them too. The main difference between manually passing the flags and using the configure option is that the latter also makes branch protection the default in GCC which may not be desirable in some cases.

* powerpc: Fix incorrect cache line size load in memset (bug 26332)Florian Weimer2020-08-031-2/+2
| | | | | | | | | | | | | | | | __GLRO loaded the word after the requested variable on big-endian PowerPC, where LOWORD is 4. This can cause the memset implement go wrong because the masking with the cache line size produces wrong results, particularly if the loaded value happens to be 1. The __GLRO macro is not used in any place where loading the lower 32-bit word of a 64-bit value is desired, so the +4 offset is always wrong. Fixes commit 18363b4f010da9ba459b13310b113ac0647c2fcc ("powerpc: Move cache line size to rtld_global_ro") and bug 26332. Reviewed-by: Carlos O'Donell <carlos@redhat.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | nptl has /* Opcodes and data types for communication with the signal handler to change user/group IDs. */ struct xid_command { int syscall_no; long int id[3]; volatile int cntr; volatile int error; }; /* This must be last, otherwise the current thread might not have permissions to send SIGSETXID syscall to the other threads. */ result = INTERNAL_SYSCALL_NCS (cmdp->syscall_no, 3, cmdp->id[0], cmdp->id[1], cmdp->id[2]); But the second argument of setgroups syscal is a pointer: int setgroups (size_t size, const gid_t *list); But on x32, pointers passed to syscall must have pointer type so that they will be zero-extended. The kernel XID arguments are unsigned and do not require sign extension. Change xid_command to struct xid_command { int syscall_no; unsigned long int id[3]; volatile int cntr; volatile int error; }; so that all arguments are zero-extended. A testcase is added for x32 and setgroups returned with EFAULT when running as root without the fix.

| | | | | | | | | | | Make glibc MTE-safe on systems where MTE is available. This allows using heap tagging with an LD_PRELOADed malloc implementation that enables MTE. We don't document this as guaranteed contract yet, so glibc may not be MTE safe when HWCAP2_MTE is set (older glibcs certainly aren't). This is mainly for testing and debugging. The HWCAP flag is not exposed in public headers until Linux adds it to its uapi. The HWCAP value reservation will be in Linux 5.9.

* aarch64: Respect p_flags when protecting code with PROT_BTISzabolcs Nagy2020-07-241-1/+8
| | | | | | | | | | | | Use PROT_READ and PROT_WRITE according to the load segment p_flags when adding PROT_BTI. This is before processing relocations which may drop PROT_BTI in case of textrels. Executable stacks are not protected via PROT_BTI either. PROT_BTI is hardening in case memory corruption happened, it's value is reduced if there is writable and executable memory available so missing it on such memory is fine, but we should respect the p_flags and should not drop PROT_WRITE.
