Subject: Re: ELF loader rejects older glibc binary
As was suggested, I tried paxctl:
dcp/usr/local/Brother/Printer/DCP7065DN# paxctl -c -pem lpd/rawtobr3
file lpd/rawtobr3 had a PT_GNU_STACK program header, converted
dcp/usr/local/Brother/Printer/DCP7065DN# ldd lpd/rawtobr3
ldd: lpd/rawtobr3: Not a valid dynamic program
dcp/usr/local/Brother/Printer/DCP7065DN# strace ldd lpd/rawtobr3
execve("/usr/bin/ldd", ["ldd", "lpd/rawtobr3"], [/* 19 vars */]) = 0
open("lpd/rawtobr3", O_RDONLY|O_LARGEFILE) = 3
read(3, "\177ELF\1\1\1\0\0\0\0\0\0\0\0\0\2\0\3\0\1\0\0\0\324\207\4\0104\0\0\0"..., 936) = 936
mmap2(0x8048000, 49152, PROT_READ|PROT_EXEC, MAP_PRIVATE, 3, 0) = 0x4ed25000
munmap(0x4ed25000, 49152) = 0
writev(2, [{"ldd: lpd/rawtobr3: Not a valid d"..., 47}, {NULL, 0}], 2ldd: lpd/rawtobr3: Not a valid dynamic program
) = 47
exit_group(1) = ?
+++ exited with 1 +++
That's all I know.
Thanks,
Isaac Dunham
