Bug description:
[Impact]
sysdig-dkms fails to build on arm64 with the latest impish kernel
(5.13):
/var/lib/dkms/sysdig/0.27.1/build/main.c:1942:28: error: ‘SYSCALL_TABLE_ID0’
undeclared (first use in this function); did you mean ‘SYSCALL_TABLE_SIZE’?
1942 | table_index = id - SYSCALL_TABLE_ID0;
| ^~~~~~~~~~~~~~~~~
| SYSCALL_TABLE_SIZE
/var/lib/dkms/sysdig/0.27.1/build/main.c:1942:28: note: each undeclared
identifier is reported only once for each function it appears in
/var/lib/dkms/sysdig/0.27.1/build/main.c: In function ‘syscall_exit_probe’:
/var/lib/dkms/sysdig/0.27.1/build/main.c:2019:28: error: ‘SYSCALL_TABLE_ID0’
undeclared (first use in this function); did you mean ‘SYSCALL_TABLE_SIZE’?
2019 | table_index = id - SYSCALL_TABLE_ID0;
| ^~~~~~~~~~~~~~~~~
| SYSCALL_TABLE_SIZE
[Test case]
$ sudo apt install sysdig-dkms
[Fix]
SYSCALL_TABLE_ID0 needs to be properly defined for arm64.
[Where problems could occur]
If the syscall table base ID changes on arm64 we may experience kernel
panics due to memory access violations or sysdig may report incorrect
result.
