+Subject: [PATCH] HPack: fix a Yoda Condition
+
+Putting the variable on the LHS of a relational operation makes the
+expression easier to read. In this case, we find that the whole
+expression is nonsensical as an overflow protection, because if
+name.size() + value.size() overflows, the result will exactly _not_
+be > max() - 32, because UB will have happened.
+
+To be fixed in a follow-up commit.
+
+As a drive-by, add parentheses around the RHS.

+Subject: [PATCH] HPack: fix incorrect integer overflow check
+
+This code never worked:
+
+For the comparison with max() - 32 to trigger, on 32-bit platforms (or
+Qt 5) signed interger overflow would have had to happen in the
+addition of the two sizes. The compiler can therefore remove the
+overflow check as dead code.
+
+On Qt 6 and 64-bit platforms, the signed integer addition would be
+very unlikely to overflow, but the following truncation to uint32
+would yield the correct result only in a narrow 32-value window just
+below UINT_MAX, if even that.
+
+Fix by using the proper tool, qAddOverflow.
+
+Manual conflict resolutions:
+ - qAddOverflow doesn't exist in Qt 5, use private add_overflow
+   predecessor API instead
