From f80fe0e68686060e861338cf7b3b32e0637b3e0b Mon Sep 17 00:00:00 2001 From: Thomas Petazzoni Date: Thu, 4 Aug 2016 10:13:09 +0200 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: Populating /dev using udev: [ 6.186817] udevd[1204]: starting version 3.1.5 [ 6.191662] udevd[1204]: syscall 384 [ 6.195217] Code: aa0503e4 aa0603e5 aa0703e6 d4000001 (b13ffc1f) [ 6.201291] CPU: 4 PID: 1204 Comm: udevd Not tainted 4.7.0+ #1 [ 6.207079] Hardware name: ARM Juno development board (r2) (DT) [ 6.212954] task: ffff800976421900 task.stack: ffff800975610000 [ 6.218825] PC is at 0xffff97f12234 [ 6.222281] LR is at 0x41b15c [ 6.225214] pc : [<0000ffff97f12234>] lr : [<000000000041b15c>] pstate: 80000000 [ 6.232544] sp : 0000ffffcf9b3870 [ 6.235828] x29: 0000ffffcf9b3870 x28: 0000000000428218 [ 6.241110] x27: 0000000000000000 x26: 000000000042a7e3 [ 6.246395] x25: 0000ffffcf9b39c8 x24: 0000000000428000 [ 6.251670] x23: 0000000000449000 x22: 0000000000449678 [ 6.256946] x21: 0000000000000010 x20: 0000000000449000 [ 6.262233] x19: 0000000000449678 x18: 0000000000000000 [ 6.267507] x17: 0000ffff97f12210 x16: 0000000000449440 [ 6.272779] x15: 0000ffff97e4f730 x14: 0000ffff98050cb8 [ 6.278060] x13: 000000000000033c x12: 00000000000004b4 [ 6.283331] x11: 0000000000000000 x10: 0101010101010101 [ 6.288604] x9 : 0000000000001010 x8 : 0000000000000180 [ 6.293882] x7 : ffffffffffffffff x6 : ffffffffffffffff [ 6.299154] x5 : 00000000271e36c0 x4 : 0007061c00190d07 [ 6.304426] x3 : 00000000271e36d0 x2 : 0000000000000001 [ 6.309705] x1 : 0000000000000010 x0 : 0000000000449678 [ 6.314976] [ 6.398734] sky2 0000:08:00.0 enp8s0: renamed from eth0 Reported-by: Kevin Hilman Signed-off-by: Thomas Petazzoni --- src/shared/missing.h | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/src/shared/missing.h b/src/shared/missing.h index 9031119..5ad5997 100644 --- a/src/shared/missing.h +++ b/src/shared/missing.h @@ -47,8 +47,10 @@ # define __NR_getrandom 318 # elif defined(__i386__) # define __NR_getrandom 355 -# elif defined(__arm__) || defined(__aarch64__) +# elif defined(__arm__) # define __NR_getrandom 384 +# elif defined(__aarch64__) +# define __NR_getrandom 278 # elif defined(__ia64__) # define __NR_getrandom 1339 # elif defined(__m68k__) -- 2.7.4
