Do you have debug info that'd point to a code line?
I have never heard of this.
I don't actually know how to get a line of code out of those
hex offsets...
Someone told me many years ago..but I lost that information :P
Err, I never remember either, I think Luis knows the gdb thing ... I
usually use "objdump -dS"
gdb net/mac80211/mac80211.ko
l *(ieee80211_stop_tx_ba_session+0x14/0x84)
Oops I meant:
gdb net/mac80211/mac80211.ko
l *(ieee80211_stop_tx_ba_session+0x14)
Thank!
I had to re-compile with debugging symbols, and added kgdb (hopefully
that won't mess anything up).
Reading symbols from /home/greearb/kernel/2.6/wireless-testing-dbg.p4s/net/mac80211/mac80211.ko...done.
(gdb) l *(ieee80211_stop_tx_ba_session+0x14)
0x54fe is in ieee80211_stop_tx_ba_session (/home/greearb/git/linux.wireless-testing/net/mac80211/agg-tx.c:595).
590
591 int ieee80211_stop_tx_ba_session(struct ieee80211_sta *pubsta, u16 tid)
592 {
593 struct sta_info *sta = container_of(pubsta, struct sta_info, sta);
594 struct ieee80211_sub_if_data *sdata = sta->sdata;
595 struct ieee80211_local *local = sdata->local;
596 struct tid_ampdu_tx *tid_tx;
597 int ret = 0;
598
599 trace_api_stop_tx_ba_session(pubsta, tid);
I'm not sure I quite got the hang of kgdb yet, but hoping to get that working
and reproduce with it enabled...
Thanks,
Ben
