The driver may reject offchannel TX operation if the requested wait time
is longer than what the driver indicates as the maximum
remain-on-channel time. Two of the P2P action frame cases used long
enough wait times (1000 ms for DevDisc and 5000 ms for SD) that could go
beyond the limit with some drivers. Fix these to limit the maximum wait
to what the driver indicates as supported.

This fixes an issue where a driver using the deprecated set_ieee8021x()
callback did not include rsn_pairwise bits in the driver configuration
even if mixed WPA+WPA2 configuration was used. This could result, e.g.,
in CCMP not being enabled properly when wpa_pairwise=TKIP and
rsn_pairwise=CCMP was used in the configuration. Fix this by using
bitwise OR of the wpa_pairwise and rsn_pairwise values to allow the
driver to enable all pairwise ciphers.
In addition, make the newer set_ap() driver_ops use the same bitwise OR
design instead of picking between rsn_pairwise and wpa_pairwise. This
makes the code paths consistent and can also fix issues with mixed mode
configuration with set_ap().

If the peer provides a username with large part of it being non-ASCII
characters, the previously used buffers may not have been long enough to
include the full string in debug logs and database search due to forced
truncation of the string by printf_encode(). Avoid this by increasing
the buffer sizes to fit in the maximum result.
Signed-off-by: Jouni Malinen <jouni@qca.qualcomm.com>
The off-by-one error in printf_encode() bounds checking could have
allowed buffer overflow with 0x00 being written to the memory position
following the last octet of the target buffer. Since this output is used
as \0-terminated string, the following operation would likely read past
the buffer as well. Either of these operations can result in the process
dying either due to buffer overflow protection or by a read from
unallowed address.
This has been seen to cause wpa_supplicant crash on OpenBSD when control
interface client attaches (debug print shows the client socket address).
Similarly, it may be possible to trigger the issue in RADIUS/EAP server
implementation within hostapd with a suitable constructed user name.

I got the below prints on a particular Android platform:
I/wpa_supplicant( 2637): nl80211: send_and_recv->nl_recvmsgs failed: 20
I/wpa_supplicant( 2637): nl80211: send_and_recv->nl_recvmsgs failed: 20
In JellyBean libnl_2 code, I see that the nl_recvmsgs returns postive values
too. In some cases, nl_recvmgs return the output of nl_recv function. nl_recv
function can return Number of bytes read, 0 or a negative error code.
Looks like this positive return value for nl_recvmsgs may be specific to
Android. While this is not how the API is supposed to work, this does no
harm with upstream libnl which returns only 0 or -1 from the function.

Couple of code paths in hostapd.c could have left hapd->drv_priv

Commit 04eff7d5ba or something around that
timeframe may have caused a regression on how drv->if_indices gets used
with wpa_supplicant. Most (curretly likely all) wpa_supplicant virtual
interface use cases should not actually use this. This could result in
issues with P2P group interfaces delivering events to incorrect
interface (parent rather than the group interface). The previous commit
removed some of the issues, but more complete fix is to undo some of
those merged hostapd/wpa_supplicant operations.
Filter add_ifidx() uses based on hostapd vs. wpa_supplicant and iftype
to get closer to the earlier wpa_supplicant behavior for the driver
events from virtual interfaces.

It is possible for a virtual interface to be added and removed by
different parent interfaces. This can happen, e.g., with P2P group
interfaces if the P2P parent interface does not happen to be the first
entry in the wpa_supplicant global interface list. That first entry is
used to remove the group interface while the addition would have
happened with the dedicated P2P management interface.
This can result in the interface that added a new virtual interface
getting stuck with an obsolete ifindex value in the drv->if_indeces list
and as such, deliver some extra events to incorrect destination wpa_s
instance. In particular, this can result in INTERFACE_DISABLED event
from deletion of a P2P group interface getting delivered incorrectly to
the parent wpa_s instance which would disable that interface even though
the interface remains in enabled state.
Fix this by clearing the removed interface from all if_indeces lists
instead of just the one that was used to delete the interface. This is
the simplest approach since the ifindex is unique and there is no need
to track which interface added the new virtual interface to always hit
the same one when removing the interface.
