++and variables of such types store the entire value.
++For instance, an array variable provides the storage (the variables)
++for all elements of the array.
++The respective zero values are specific to the
++value's types; they are never nil.
++

++
++

++Non-nil pointer, function, slice, map, and channel values contain references
++to underlying data which may be shared by multiple values:
++

++
++
    
++
  • 
++	A pointer value is a reference to the variable holding
++	the pointer base type value.
++
    • 
++
  • 
++	A function value contains references to the (possibly
++	anonymous) function
++	and enclosed variables.
++
    • 
++
  • 
++	A slice value contains the slice length, capacity, and
++	a reference to its underlying array.
++
    • 
++
  • 
++	A map or channel value is a reference to the implementation-specific
++	data structure of the map or channel.
++
    • 
++

++
++

++An interface value may be self-contained or contain references to underlying data
++depending on the interface's dynamic type.
++The predeclared identifier nil is the zero value for types whose values
++can contain references.
++

++
++

++When multiple values share underlying data, changing one value may change another.
++For instance, changing an element of a slice will change
++that element in the underlying array for all slices that share the array.

+-Package pbkdf2 implements the key derivation function PBKDF2 as defined in RFC
+-2898 / PKCS #5 v2.0.
+-
+-A key derivation function is useful when encrypting data based on a password
+-or any other not-fully-random data. It uses a pseudorandom function to derive
+-a secure encryption key based on the password.
+-
+-While v2.0 of the standard defines only one pseudorandom function to use,
+-HMAC-SHA1, the drafted v2.1 specification allows use of all five FIPS Approved
+-Hash Functions SHA-1, SHA-224, SHA-256, SHA-384 and SHA-512 for HMAC. To
+-choose, you can pass the `New` functions from the different SHA packages to
+-pbkdf2.Key.

Subject: [PATCH 59/93] Add reference to a patch

I realized that I didn't document correctly the
fix_cgo_panic-with-gcc15-in-368.patch patch and it's a complex one.
I included the gcc issue related to the solution:
https://gcc.gnu.org/PR118497

--While v2.0 of the standard defines only one pseudorandom function to use,

-+// Loop resets the benchmark timer the first time it is called in a benchmark,
-+// so any setup performed prior to starting the benchmark loop does not count
-+// toward the benchmark measurement. Likewise, when it returns false, it stops
-+// the timer so cleanup code is not measured.
-+//
-+// The compiler never optimizes away calls to functions within the body of a
-+// "for b.Loop() { ... }" loop. This prevents surprises that can otherwise occur
-+// if the compiler determines that the result of a benchmarked function is
-+// unused. The loop must be written in exactly this form, and this only applies
-+// to calls syntactically between the curly braces of the loop. Optimizations
-+// are performed as usual in any functions called by the loop.
-+//
-+// After Loop returns false, b.N contains the total number of iterations that

+Subject: [PATCH] [release-branch.go1.24] runtime: cleanup M vgetrandom state before dropping P
+
+When an M is destroyed, we put its vgetrandom state back on the shared
+list for another M to reuse. This list is simply a slice, so appending
+to the slice may allocate. Currently this operation is performed in
+mdestroy, after the P is released, meaning allocation is not allowed.
+
+More the cleanup earlier in mdestroy when allocation is still OK.
+
+Also add //go:nowritebarrierrec to mdestroy since it runs without a P,
+which would have caught this bug.
+
+Fixes #73144.
+For #73141.

-Subject: [PATCH] [release-branch.go1.24] runtime: cleanup M vgetrandom state before dropping P
-
-When an M is destroyed, we put its vgetrandom state back on the shared
-list for another M to reuse. This list is simply a slice, so appending
-to the slice may allocate. Currently this operation is performed in
-mdestroy, after the P is released, meaning allocation is not allowed.
-
-More the cleanup earlier in mdestroy when allocation is still OK.
-
-Also add //go:nowritebarrierrec to mdestroy since it runs without a P,
-which would have caught this bug.
-
-Fixes #73144.
-For #73141.
