| 2025-08-11 | check_users: Use sd_get_uids instead of sd_get_session | Lorenz Kästle | 1 | -1/+1 | |
| Previously check_users in combination with systemd used sd_get_sessions (3) to aquire the number of users, probably with the idea that every users opens a session. Turns out, that a user can have multiple sessions and we only really want to know how many users there are. This commit changes to sd_get_uids (3) to achieve that target. | |||||

| 2025-07-11 | check_ssh: Fix buffer overflow | Richard Laager | 1 | -3/+5 | |
| A buffer overflow was occurring when the server responded with: Exceeded MaxStartups\r\n glibc would then abort() with the following output: *** buffer overflow detected ***: terminated It was the memset() that was overflowing the buffer. But the memmove() needed fixing too. First off, there was an off-by-one error in both the memmove() and memset(). byte_offset was already set to the start of the data _past_ the newline (i.e. len + 1). For the memmove(), incrementing that by 1 again lost the first character of the additional output. For the memset(), this causes a buffer overflow. Second, the memset() has multiple issues. The comment claims that it was NULing (sic "null") the "rest". However, it has no idea how long the "rest" is, at this point. It was NULing BUFF_SZ - byte_offset + 1. After fixing the off-by-one / buffer overflow, it would be NULing BUFF_SZ - byte_offset. But that doesn't make any sense. The length of the first line has no relation to the length of the second line. For a quick-and-dirty test, add something like this just inside the while loop: memcpy(output, "Exceeded MaxStartups\r\nnext blah1 blah2 blah3 blah4\0", sizeof("Exceeded MaxStartups\r\nnext blah1 blah2 blah3 blah4\0")); And, after the memmove(), add: printf("output='%s'\n", output); If you fix the memset() buffer overflow, it will output: output='ext blah1 blah2 blah3 ' As you can see, the first character is lost. If you then fix the memmove(), it will output: output='next blah1 blah2 blah3' Note that this is still losing the "blah4". After moving the memset() after byte_offset is set to the new strlen() of output, then it works correctly: output='next blah1 blah2 blah3 blah4' Signed-off-by: Richard Laager <rlaager@wiktel.com> | |||||

| 2025-06-12 | Implement new fping options for fping 5.2 and 5.3 | Lorenz Kästle | 2 | -8/+96 | |
| fping 5.2 and 5.3 add some new useful command line options which this commit add to check_fping. These are: * --fwmark - sets a firewall mark in the packages to make them identifiable (fping 5.2) * --icmp-timestamp - fping uses ICMP timestamp instead of ICMP Echo (fping 5.2) * --check-source - fping discards replies which originate not from the target address (fping 5.2) The fping release notes describe theses options ( https://github.com/schweikert/fping/releases ) in a little bit more detail. Currently the help display for those options is only shown when fping was available in the appropriate version during compilation. | |||||

| If fping is used with a target that has dual stack v4/v6, then due to the logic during command construction, ipv4 will never be checked as v6 is preferred by fping. This explicitly flags -4/-6 when it is requested by the user. | |||||
