Patches for slstatus 1.1
========================

These patches are backported from the slstatus upstream repository
(https://git.suckless.org/slstatus) and applied at build time by
the SlackBuild script.

01-memory-lscanf.patch
  commit 8723e8b8c69c08bae8abe02ea1f4a49758b8bdfc
  Author: drkhsh <me@drkhsh.at>
  Date:   Thu, 24 Jul 2025

  More concise memory calculation on Linux. Introduces lscanf() for
  flexible /proc/meminfo parsing, taking shared and reclaimable memory
  into account to match the output of free(1). Also fixes corner cases
  where the order of fields in /proc/meminfo is not strictly defined.

02-volume-null-deref.patch
  commit 6fa36bad9f74154d4bf3be834ada93e04bf737e1
  Author: Chris Billington <emulti@disroot.org>
  Date:   Fri, 21 Nov 2025

  Avoid NULL dereference in onval() when an sndio device switch occurs
  and the control address is not found in the list.

03-wifi-ioctl-retry.patch
  commit 4f61bbbd8e9278c75f29e7853ae8922717261d2d
  Author: drkhsh <me@drkhsh.at>
  Date:   Thu, 12 Feb 2026

  Always retry ioctl(SIOCGIFINDEX) for the wifi interface index instead
  of caching a potentially stale result. Fixes cases where the interface
  does not exist at slstatus startup (e.g. iwd destroying and recreating
  interfaces depending on service state).

04-battery-buffer-overflow.patch
  commit 98769dfed7266b5a9959162e03bee1ddfaf5ecb4
  Author: drkhsh <me@drkhsh.at>
  Date:   Thu, 12 Feb 2026

  Fix buffer overflow in battery state parsing. "Not charging" is 12
  characters; the format specifier %12[a-zA-Z ] reads up to 12 chars
  plus a NUL terminator (13 bytes) into a 12-byte buffer. Increases
  state buffer to 13 in both battery_state() and battery_remaining().

05-fmt-human-no-space.patch
  local patch
  Author: Ricardson Williams <r1w1s1@fastmail.com>
  Date:   Thu, 14 May 2026

  Remove the space between the numeric value and unit prefix in
  fmt_human() output:

    "2.4 Gi" -> "2.4Gi"

  This produces more compact status output, which is useful for
  narrow status bars and minimalist desktop setups.
