When the kernel headers in the toolchain don't provide __NR_getrandom, eudev has a predefined set of values. However, the provided value for ARM64 is incorrect, and causes a runtime problem on this architecture when old kernel headers (not providing __NR_getrandom) are used. This commit adds a patch to eudev to fix this issue. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Tested-by: Kevin Hilman <khilman@baylibre.com>

Subject: [PATCH] src/shared/missing.h: fix getrandom system call number on
|
|
ARM64
|
|
|
|
The getrandom() system call number is indeed 384 on ARM, but it is not
|
|
the same on ARM64. ARM64 uses the asm-generic headers, including for
|
|
system call numbers, so the getrandom() system call number on ARM64 is
|
|
278. This fixes runtime issues of eudev on ARM64, such as:
