* rtld/arm: fix initial-exec (IE) thread-local storage relocationR. Christian McDonald2023-11-031-2/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | net/frr[89] revealed an interesting edge-case on arm when dynamically linking a shared library that declares more than one static TLS variable with at least one using the "initial-exec" TLS model. In the case of frr[89], this library was libfrr.so which essentially does the following: #include <stdio.h> #include "lib.h" static __thread int *a __attribute__((tls_model("initial-exec"))); void lib_test() { static __thread int b = -1; printf("&a = %p\n", &a); printf(" a = %p\n", a); printf("\n"); printf("&b = %p\n", &b); printf(" b = %d\n", b); } Allocates a file scoped `static __thread` pointer with tls_model("initial-exec") and later a block scoped TLS int. Notice in the above minimal reproducer, `b == -1`. The relocation process does the wrong thing and ends up pointing both `a` and `b` at the same place in memory. The output of the above in the broken state is: &a = 0x4009c018 a = 0xffffffff &b = 0x4009c018 b = -1 With the patch applied, the output becomes: &a = 0x4009c01c a = 0x0 &b = 0x4009c018 b = -1 Reviewed by: kib Sponsored by: Rubicon Communications, LLC ("Netgate") Differential Revision: https://reviews.freebsd.org/D42415/

* rtld: introduce STATIC_TLS_EXTRAStephen J. Kiernan2023-10-3010-12/+35
| | | | | | | | | | | | | | | | | | The new STATIC_TLS_EXTRA variable provides a means for applications to increases the size of the extra static TLS space allocated by rtld beyond the default of '128'. This extra static TLS space is used for objects loaded with dlopen. The value specified in the variable must be no less than the default value and no greater than the maximum allowed value for size_t type. If an invalid value is specified, rtld will ignore it and just use the default value. The rtld(1) man page is updated to document this new option. Obtained from: Juniper Networks, Inc.

* jail: avoid a clash with /etc/jail.conf.d between rc and jail(8)Jamie Gritton2023-09-251-1/+3
| | | | | | | | | | | | | | | | | | | | | | Since 13.1, /etc/rc.d/jail has looked for a per-jail config file in /etc/jail.conf.d. For RELENG 14, the ".include" directive was added to jail(8), with a sample line in the jail.conf(5) man page that includes "/etc/jail.conf.d/*.conf". These two use cases don't work together. When the jail.conf.d files are included from a master jail.conf, the files in jail.conf.d are likely to hold only partial configurations, and shouldn't be directly loaded by rc.d/jail. But there are existing configurations that depend on the current rc.d behavior. While users could be advised not to include from /etc/jail.conf.d, it's the natural choice even if not mentioned in jail.conf.5. The workaround is for rc.d/jail to continue to load the individual files, but only when /etc/jail.conf doesn't include from that directory (via a simple grep test), This allows the current use while not breaking the previous use.

* rc.subr: don't require service to be enabled for `status`Daniel Tameling2023-09-211-2/+3
| | | | | | | | | | | | | | For a service that sets an rcvar, there is a check whether it has been enabled before the actual command is executed. If the check fails, one gets a message to enable it and the returned exit status is 0. However, this is usually undesirable for the status command, which is a) supposed to check whether the service is running anyway and b) returns a non-zero exit code if that is not the case. Thus, skip the check for the status command. PR: 272282 Reviewed by: emaste MFC after: 3 days
