fix wifi buffer overflows on Linux

2026-06-23T22:12:47+00:00

replace strcpy of interface name into ifr_name (IFNAMSIZ=16) with
bounds-checked snprintf. add one byte to resp buffer so NUL-terminating
the SSID at resp boundary does not write out of bounds.

wifi: always retry ioctl for ifindex

2026-02-12T21:46:02+00:00

ifindex() caches the result of ioctl(SIOCGIFINDEX) and never
retries it, since the interface name strcmp succeeds after the
first call. if the interface does not exist when slstatus starts
(e.g. iwd with default config destroys/recreates interfaces
depending on service state), the ioctl fails and the stale
result is returned on all subsequent calls.

various: Put paths into defines to avoid line wraps

2022-10-27T23:01:10+00:00

Long, wrapped, multi-line if statements suck to read.
This fixes readability in the worst places by packing format strings for
paths into defines.

components/*.c: include slstatus.h

2022-10-26T21:32:07+00:00

this gives the compiler a chance to check weather the prototype and
definiton matches or not, which would catch issues like 3c47701.
