The old BSD 4.4 definition (not used by Linux) was not 64b-proof: the cmsg_data field is supposed to CMSG_ALIGN'ed (as can be also seen in the CMSG_LEN macro). Suggested-by: Diego Nieto Cid <dnietoc@gmail.com>

2024-12-31elf: Do not change stack permission on dlopen/dlmopenAdhemerval Zanella2-1/+2
If some shared library loaded with dlopen/dlmopen requires an executable stack, either implicitly because of a missing GNU_STACK ELF header (where the ABI default flags implies in the executable bit) or explicitly because of the executable bit from GNU_STACK; the loader will try to set the both the main thread and all thread stacks (from the pthread cache) as executable. Besides the issue where any __nptl_change_stack_perm failure does not undo the previous executable transition (meaning that if the library fails to load, there can be thread stacks with executable stacks), this behavior was used on a CVE [1] as a vector for RCE. This patch changes that if a shared library requires an executable stack, and the current stack is not executable, dlopen fails. The change is done only for dynamically loaded modules, if the program or any dependency requires an executable stack, the loader will still change the main thread before program execution and any thread created with default stack configuration.

2024-11-12linux: Add support for getrandom vDSOAdhemerval Zanella1-1/+3
Linux 6.11 has getrandom() in vDSO. It operates on a thread-local opaque state allocated with mmap using flags specified by the vDSO. Multiple states are allocated at once, as many as fit into a page, and these are held in an array of available states to be doled out to each thread upon first use, and recycled when a thread terminates. As these states run low, more are allocated. To make this procedure async-signal-safe, a simple guard is used in the LSB of the opaque state address, falling back to the syscall if there's reentrancy contention. Also, _Fork() is handled by blocking signals on opaque state allocation (so _Fork() always sees a consistent state even if it interrupts a getrandom() call) and by iterating over the thread stack cache on reclaim_stack. Each opaque state will be in the free states list (grnd_alloc.states) or allocated to a running thread. The cancellation is handled by always using GRND_NONBLOCK flags while calling the vDSO, and falling back to the cancellable syscall if the kernel returns EAGAIN (would block). Since getrandom is not defined by POSIX and cancellation is supported as an extension, the cancellation is handled as 'may occur' instead of 'shall occur' [1], meaning that if vDSO does not block (the expected behavior) getrandom will not act as a cancellation entrypoint. It avoids a pthread_testcancel call on the fast path (different than 'shall occur' functions, like sem_wait()). It is currently enabled for x86_64, which is available in Linux 6.11, and aarch64, powerpc32, powerpc64, loongarch64, and s390x, which are available in Linux 6.12.
