ccf79ab256 browser-android: Use execv() directly instead of os_exec()
This allows the URL to be passed as a single argument to the program
instead of getting split into multiple by os_exec(). This makes the
operation more robust for cases where the URL could have been received
from an external source and could potentially add extra arguments to the
command line.

In addition, fix the /system/bin/input execution by using system() for
it instead of execv() through os_exec(). /system/bin/input is a script
that execv() won't be able to run. Since the full command line is
specified, system() can be used for this. The keycode is also changed
from 3 to KEYCODE_HOME to make this work with current Android version.

a8833b84f4 util: Don't use "\e"
'\e' representing ESC (0x1b) is not C standard, it's an GNU extension.
https://gcc.gnu.org/onlinedocs/gcc/Character-Escapes.html#Character-Escapes

Since the code also compiles on Windows with Microsoft compiler, we
should use '\033' instead.

Note: I didn't try to build the whole wpa_supplicant on Windows, so I
don't know if it still builds (I have no Visual Studio 2005 for a quick
test). I just needed the string conversion routines for the P"" syntax
in both directions.

9c196f7703 HTTP: Fix OCSP status check
Due to a missing curly brackets, the OCSP status checking was not
working in the expected way. Instead of allowing optional-OCSP
configuration to accept connection when OCSP response was ready, all
such cases were marked as hard failures. In addition, the debug prints
were not necessarily accurate for the mandatory-OCSP-but-no-response
case (CID 72694, CID 72704).

afc3c8b07f Add constant time memory comparison function os_memcmp_const
This function is meant for comparing passwords or hash values where
difference in execution time could provide external observer information
about the location of the difference in the memory buffers. The return
value does not behave like os_memcmp(), i.e., os_memcmp_const() cannot
be used to sort items into a defined order. Unlike os_memcmp(),
execution time of os_memcmp_const() does not depend on the contents of
the compared memory buffers, but only on the total compared length.

5dff6dff63 Fix off-by-one bounds checking in printf_encode()
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.

f0356ec85c eloop: Add epoll option for better performance
This patch adds epoll option for the eloop implementation. This can be
selected with the CONFIG_ELOOP_EPOLL=y build option.

[merit]
See Table1.

Table1. comparison table
+--------+--------+-----------+------------+-------------+
|        | add fd | remove fd | prepare fd | dispatch fd |
+--------+--------+-----------+------------+-------------+
| select | O(1)   | O(1)      | O(N)       | O(N)        |
+--------+--------+-----------+------------+-------------+
| poll   | O(1)   | O(1)      | O(N)       | O(N)        |
+--------+--------+-----------+------------+-------------+
| epoll  | O(1)   | O(1)      | 0          | O(M)        |
+--------+--------+-----------+------------+-------------+
"add fd" is addition of fd by eloop_sock_table_add_sock().
"remove fd" is removal of fd by eloop_sock_table_remove_sock().
"prepare fd" is preparation of fds before wait in eloop_run().
"dispatch fd" is dispatchment of fds by eloop_sock_table_dispatch().
"N" is all watching fds.
"M" is fds which could be dispatched after waiting.

As shown in Table1, epoll option has better performance on "prepare fd" column.
Because select/poll option requires setting fds before every select()/poll().
But epoll_wait() doesn't need it.

And epoll option has also better performance on "dispatch fd" column.
Because select/poll option needs to check all registered fds to find out
dispatchable fds. But epoll option doesn't require checking all registered fds.
Because epoll_wait() returns dispatchable fd set.

So epoll option is effective for GO/AP functionality.

[demerit]
The epoll option requires additional heap memory. In case of P2P GO, it is
about 8K bytes.

c70c37500b SCARD: Fix GSM authentication on USIM
scard_gsm_auth() used SIM_CMD_GET_RESPONSE for both SIM and USIM. Convert
the command into USIM_CMD_GET_RESPONSE for USIM.

Since commit eb32460029 ("Fix switching from EAP-SIM to EAP-AKA/AKA'")
EAP-SIM is using the USIM if available. This triggers a probably ancient
bug in scard_gsm_auth(), which results in sending the wrong get response
command to the USIM. Thus, EAP-SIM stopped to work after this change on
USIMs that expect the proper command.

21611ea9fd edit: Increase buffer size to 4096 bytes
wpa_supplicant and wpa_cli had already moved to allowing up to 4096 byte
buffer size to be used for control interface commands. This was limited
by the line edit buffer in interactive mode. Increase that limit to
match the other buffers to avoid artificially truncating long commands.

a09ffd5f2f Fix req_scan-deplete-timeout and update eloop API for this
Commit e2f5a9889a was supposed to prevent
new scan request from pushing out the old one. However, it did not
really do that since eloop_deplete_timeout() returned 0 both for the
case where the old timeout existed (and was sooner) and if the old
timeout did not exist. It returned 1 only for the case where an old
timeout did exist and was larger than the new requested value. That case
used to result in wpa_supplicant_req_scan() rescheduling the timeout,
but hew code in eloop_deplete_timeout() did the exact same thing and as
such, did not really change anything apart from the debug log message.

Extend the eloop_deplete_timeout() (and eloop_replenish_timeout() for
that matter since it is very similar) to return three different values
based on whether the timeout existed or not and if yes, whether it was
modified. This allows wpa_supplicant_req_scan() to schedule a new
timeout only in the case there was no old timeout.
