OK good -- that patch was way too complex for just being able display
those additional section addresses. Plus, for example, it resulted in
this when run on RHEL5:
... [ cut ] ...
But I will keep your first module-section-address-display patch
queued for crash-6.0.2.
Hello Toshi,
Actually, after using this patch a bit, I've found that sometimes
it can be more confusing than helpful, especially with kernel modules
that only have a small number of symbols. Plus it does things like
this, which is not particularly helpful:
crash> sym -q odata
ffffffff8007f2a4 (t) .text.mark_rodata_ro
ffffffff8007f2a4 (T) mark_rodata_ro
ffffffff80274000 (r) .rodata
ffffffff80274000 (R) __start_rodata
ffffffff802ecbac (A) __end_rodata
ffffffff88004f20 (S) _MODULE_SECTION_START [.rodata] [ehci_hcd]
ffffffff88005140 (S) _MODULE_SECTION_END [.rodata] [ehci_hcd]
ffffffff88014ee0 (S) _MODULE_SECTION_START [.rodata] [ohci_hcd]
ffffffff88015100 (S) _MODULE_SECTION_END [.rodata] [ohci_hcd]
ffffffff88024160 (S) _MODULE_SECTION_START [.rodata] [uhci_hcd]
ffffffff880243e0 (S) _MODULE_SECTION_END [.rodata] [uhci_hcd]
ffffffff880382c0 (S) _MODULE_SECTION_START [.rodata] [jbd]
ffffffff8803885e (S) _MODULE_SECTION_END [.rodata] [jbd]
ffffffff8805c920 (S) _MODULE_SECTION_START [.rodata] [ext3]
ffffffff8805da02 (S) _MODULE_SECTION_END [.rodata] [ext3]
ffffffff8807fe20 (S) _MODULE_SECTION_START [.rodata] [scsi_mod]
...
But presumably you had your reasons for implementing it, so I'll
keep your patch in place -- but only as an option to the "mod" command.
So in order to have module symbol lists intermingled with section
start/end address pseudo-symbols, I've added a "mod -g" flag that
can be used in conjunction with "-s" or "-S". Hopefully that works
OK for you.
Thanks,
Dave
