win32: code shrink procps_scan()

2026-07-15T15:26:35+00:00

The principal change is to replace four separate arrays (one for pids and three for time values) with a single array of structs. There are some other minor adjustments. Saves 96-144 bytes. (GitHub PR #609) Signed-off-by: Ron Yorston

fix: procps_scan: compare process creation times to ensure ppid is real

2026-07-15T14:45:39+00:00

Windows aggressively reuses PIDs of exited processes. When a new irrelevant process gets assigned the former PID of the parent of an orphaned process, `pkill -P`, `pgrep -P`, `ps -o ppid` sees the new process as the parent of the orphaned process, and PPID of the orphan is no longer 1. So in theory, all `pkill -P`, `pgrep -P` calls are potentially dangerous and possible to kill an innocent process which outlives its parent. This issue is already discussed in various Internet communities: - https://stackoverflow.com/questions/6593003/how-can-i-reliably-check-whether-one-windows-process-is-the-parent-of-another-in - https://web.archive.org/web/20140701081232/https://www.sapphiresteel.com/Blog/Killing-Trees-the-Windows-way Comparing process creation times seems a feasible mitigation that should almost always work (though not theoretically sound). The executable is added 512 bytes after the patch.

crond: build tweaks

2026-05-03T09:52:29+00:00

Using 'depends on FEATURE_SYSLOG' is unreliable because FEATURE_SYSLOG can't be set directly. A POSIX build with all applets that need syslog disabled *except* crond may fail. Revert to using 'select FEATURE_SYSLOG' in crond and exclude the unused syslog code on Windows. If crond is unable to run sendmail report this in the error message. Update all default Windows configurations. (GitHub PR #561)

wget: allow HTTPS certificate check to be skipped

2026-04-24T07:43:59+00:00

The Microsoft Windows Schannel implementation of TLS validates the server certificate. Enable the --no-check-certificate option to wget to allow these checks to be skipped. This may be useful to connect to badly configured websites. Adds 202 bytes to the x86_64 build with Schannel enabled. (GitHub issue #581)

ash: allow 'times' built-in to report process timing

2026-04-12T10:49:29+00:00

Move existing code which obtains process execution times into a separate function. Use it to allow times(2) to report execution times for the current process, though not child execution times. Change TICKS_PER_SECOND from 100 to 1000 to increase the displayed resolution of process times (though the measured resolution may well be less than this). Adds 48-80 bytes. (GitHub issue #574)
