[PATCH 0/1] libavb: fix avb_replace() OOM handling

[Josh Law <josh2@disroot.org>]

Hi folks,

Since I am a new contributor, I would like to introduce myself first. I
am 15, I am from the UK, and I write C. I am interested in lib/, ARM
devices, and Android.

Enough of the introduction. Let's talk about the patch.

avb_replace() is documented to return NULL on OOM. It already did that
before any output was built, but if a later allocation failed after the
first replacement, it returned the partial buffer instead. The callers
only treat NULL as failure, so they could keep booting with truncated AVB
bootargs.

This patch frees the partial buffer and returns NULL. The existing
callers can then report OOM instead of accepting a shortened result.
