We've seen addresses in parasite.built-in.o precalculated by linker but in some unexpected manner: readelf -WS criu/pie/parasite.built-in.o Section Headers: [Nr] Name Type Address Off Size ES Flg Lk Inf Al [ 1] .text PROGBITS 0000000000000000 000040 00400a 00 AX 0 0 16 [87] .data PROGBITS 0000000000000000 005000 000068 00 WA 0 0 4096 [88] .rodata PROGBITS 0000000000000080 005080 001016 00 A 0 0 32 (Notes: All other sections does not have SHF_ALLOC or are of size 0, so I skip them. Need to add "-specs=/usr/lib/rpm/redhat/redhat-annobin-cc1" to CFLAGS to reproduce.) Section 88 has address 0x80 in elf file but in our "consequent" addresses precalculation algorithm it should be at 0x5080: addr(.text) == 0x0 addr(.data) == 0x400a + (0x1000 - 0x400a % 0x1000) + 0x68 == 0x5068 addr(.rodata) == 0x5068 + (0x20 - 0x5068 % 0x20) == 0x5080 Probably the linker advises us to move 4096 aligned section to the beginning to save some space, but it's just a guess. So probably we should be ready to "non-consequent" alignments precalculated and just override them. https://github.com/checkpoint-restore/criu/issues/1301 Signed-off-by: Pavel Tikhomirov <ptikhomirov@virtuozzo.com> |
