# Password crypt stubbing
config MUSL_DISABLE_CRYPT_SIZE_HACK
bool "Include crypt() support for SHA256, SHA512 and Blowfish ciphers"
depends on TOOLCHAINOPTS && USE_MUSL && !EXTERNAL_TOOLCHAIN
default n
help
Enable this option to re-include crypt() support for the SHA256, SHA512 and
Blowfish ciphers. Without this option, attempting to hash a string with a salt
requesting one of these ciphers will cause the crypt() function to call stub
implementations which will always fail with errno ENOSYS. Including the ciphers
will increase the library size by about 14KB after LZMA compression.

/*
* This file defines five types of data structures: singly-linked lists,
* lists, simple queues, tail queues, and circular queues.
*
* A singly-linked list is headed by a single forward pointer. The
* elements are singly linked for minimum space and pointer manipulation
* overhead at the expense of O(n) removal for arbitrary elements. New
* elements can be added to the list after an existing element or at the
* head of the list. Elements being removed from the head of the list
* should use the explicit macro for this purpose for optimum
* efficiency. A singly-linked list may only be traversed in the forward
* direction. Singly-linked lists are ideal for applications with large
* datasets and few or no removals or for implementing a LIFO queue.
*
* A list is headed by a single forward pointer (or an array of forward
* pointers for a hash table header). The elements are doubly linked
* so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before
* or after an existing element or at the head of the list. A list
* may only be traversed in the forward direction.
*
* A simple queue is headed by a pair of pointers, one the head of the
* list and the other to the tail of the list. The elements are singly
* linked to save space, so elements can only be removed from the
* head of the list. New elements can be added to the list after
* an existing element, at the head of the list, or at the end of the
* list. A simple queue may only be traversed in the forward direction.
*
* A tail queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or
* after an existing element, at the head of the list, or at the end of
* the list. A tail queue may be traversed in either direction.
*
* A circle queue is headed by a pair of pointers, one to the head of the
* list and the other to the tail of the list. The elements are doubly
* linked so that an arbitrary element can be removed without a need to
* traverse the list. New elements can be added to the list before or after
* an existing element, at the head of the list, or at the end of the list.
* A circle queue may be traversed in either direction, but has a more
* complex end of list detection.
*
* For details on the use of these macros, see the queue(3) manual page.

Subject: [PATCH v2] Add format attribute to some function declarations
GCC and Clang are able to check the format arguments given to a
function and warn the user if there is a error in the format arguments
or if there is a potential uncontrolled format string security problem
in the code. GCC does this automatically for some functions like
printf(), but it is also possible to annotate other functions in a way
that it will check them too. This feature is used by glibc for many
functions. This patch adds the attribute to the some functions of musl
expect for these functions where gcc automatically adds it.
GCC automatically adds checks for these functions: printf, fprintf,
sprintf, scanf, fscanf, sscanf, strftime, vprintf, vfprintf and
vsprintf.
The documentation from gcc is here:

From e01b5939b38aea5ecbe41670643199825874b26c Mon Sep 17 00:00:00 2001
From: Rich Felker <dalias@aerifal.cx>
Date: Thu, 21 May 2020 23:32:45 -0400
Subject: [PATCH 2/4] don't use libc.threads_minus_1 as relaxed atomic for
skipping locks
after all but the last thread exits, the next thread to observe
libc.threads_minus_1==0 and conclude that it can skip locking fails to
synchronize with any changes to memory that were made by the
last-exiting thread. this can produce data races.
on some archs, at least x86, memory synchronization is unlikely to be
a problem; however, with the inline locks in malloc, skipping the lock
also eliminated the compiler barrier, and caused code that needed to
re-check chunk in-use bits after obtaining the lock to reuse a stale
value, possibly from before the process became single-threaded. this
in turn produced corruption of the heap state.
some uses of libc.threads_minus_1 remain, especially for allocation of
new TLS in the dynamic linker; otherwise, it could be removed
entirely. it's made non-volatile to reflect that the remaining
accesses are only made under lock on the thread list.
instead of libc.threads_minus_1, libc.threaded is now used for
skipping locks. the difference is that libc.threaded is permanently
true once an additional thread has been created. this will produce
some performance regression in processes that are mostly
single-threaded but occasionally creating threads. in the future it
may be possible to bring back the full lock-skipping, but more care
needs to be taken to produce a safe design.
