linux - How are the flags of ELF sections defined? -


using readelf -s can obtain information sections of relocatable file, however, i'm puzzled meaning of flg. in elf.h linux kernel @ linux/elf.h:

/* sh_flags */     #define shf_write       0x1 #define shf_alloc       0x2 #define shf_execinstr       0x4 #define shf_rela_livepatch  0x00100000 #define shf_ro_after_init   0x00200000 #define shf_maskproc        0xf0000000

but got

key flags:   w (write), (alloc), x (execute), m (merge), s (strings), l (large)   (info), l (link order), g (group), t (tls), e (exclude), x (unknown)   o (extra os processing required) o (os specific), p (processor specific)

so how other flags defined?
