This fixes a bug where the caller's timeval will be clobbered on Linux.
The Kernel ABI *always* modifies the timeout argument but POSIX says it
should be a const parameter. The wrapper now handles the difference and
sys_select() may be used if obtaining the remainder on Linux is needed.
The system call wrapper was wrongfully reinterpreting kernel data. The
examples/sysinfo.c program is now updated to show how to correctly use
what's returned.
libc/sock/if.h is removed because:
- it contained only IFNAMSIZ, which was also defined in
libc/sock/struct/ifreq.h
- it was not included in any file EXCEPT libc/isystem/net/if.h, which
also included the libc/sock/struct/ifreq.h
hence we remove this file, and move the IFNAMSIZ definition to
libc/sock/struct/ifreq.h which is included in isystem.
IFNAMSIZ is defined in:
- libc/sock/if.h
- libc/sock/struct/ifreq.h
we add a check in the latter to avoid a complaint when using the
amalgamated header.
* [metal] Copy program pages to extended memory at startup
* [metal] Reclaim base memory pages for later app use
* [metal] Load program pages beyond 1st 440 KiB to extended memory
o//examples/hellolua.com now runs correctly under QEMU (in
legacy BIOS mode).
* [metal] Place GDT in read/write segment
The CPU absolutely needs to alter the GDT when loading the
task register (via ltr). To account for this, I move the
GDT into a read/write data section. There is still a "rump"
read-only GDT in the text section that is used by the real
mode bootloader.
We also delay the loading of the task register (ltr) until
after the IDT and TSS are finally set up.
* [metal] Get examples/vga2.c serial output working for UEFI boot
* [metal] Get examples/vga2.c VGA output working for UEFI boot
* [metal] Allow munmap() to reclaim dynamically allocated pages
* Place TLS sections right after .text, not after embedded zip file

- Improve compatibility with Blink virtual machine
- Add non-POSIX APIs for joining threads and signal masks
- Never ever use anything except 32-bit integers for atomics
- Add some `#undef` statements to workaround `ctags` problems
This change adds a double linked list of threads, so that pthread_exit()
will know when it should call exit() from an orphaned child. This change
also improves ftrace and strace logging.
- clock_nanosleep() is now much faster on OpenBSD and NetBSD
- Thread joining is now much faster on NetBSD
- FreeBSD timestamps are now more accurate
- Thread spawning now goes faster on XNU
- Clean up the clone() code
- Clean up sigaction() code
- Add a port scanner example
- Introduce a ParseCidr() API
- Clean up our futex abstraction code
- Fix a harmless integer overflow in ParseIp()
- Use kernel semaphores on NetBSD to make threads much faster
- Exhaustively document cancellation points
- Rename SIGCANCEL to SIGTHR just like BSDs
- Further improve POSIX thread cancellations
- Ensure asynchronous cancellations work correctly
- Elevate the quality of getrandom() and getentropy()
- Make futexes cancel correctly on OpenBSD 6.x and 7.x
- Add reboot.com and shutdown.com to examples directory
- Remove underscore prefix from awesome timespec_*() APIs
- Create assertions that help verify our cancellation points
- Remove bad timespec APIs (cmp generalizes eq/ne/gt/gte/lt/lte)
